Example Question #11 : How To Find The Length Of The Side Of A Kite

Given: Regular Pentagon \(\displaystyle PENTA\) with center \(\displaystyle C\). Construct segments \(\displaystyle \overline{CP}\) and \(\displaystyle \overline{CN}\) to form Quadrilateral \(\displaystyle CPEN\).

True or false: Quadrilateral \(\displaystyle CPEN\) is a kite.

Possible Answers:

False

True

Correct answer:

True

Explanation:

Below is regular Pentagon \(\displaystyle PENTA\) with center \(\displaystyle C\), a segment drawn from \(\displaystyle C\) to each vertex - that is, each of its radii drawn.

Pentagon a

A kite is a quadrilateral with two sets of congruent adjacent sides, with the common length of one pair differing from that of the other. A regular polygon has congruent sides, so \(\displaystyle \overline{EN} \cong \overline{EP}\); also, all radii of a regular polygon are congruent, so \(\displaystyle \overline{CP} \cong \overline{CN}\). It follows by definition that Quadrilateral \(\displaystyle CPEN\) is a kite.

Example Question #21 : Kites

Kite_series_2

Using the kite shown above, find the length of side \(\displaystyle b.\)

Possible Answers:

\(\displaystyle 5\)

\(\displaystyle 14\)

\(\displaystyle 10\)

\(\displaystyle 12\)

\(\displaystyle 11\)

Correct answer:

\(\displaystyle 12\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

Thus, the length of side \(\displaystyle b=a+5\).

Since, \(\displaystyle a=\) \(\displaystyle 7\)\(\displaystyle b\) must equal \(\displaystyle 7+5=12\).  

Example Question #22 : Kites

Kite_series_2

What is the length of side \(\displaystyle a?\)

Possible Answers:

\(\displaystyle 6\)

\(\displaystyle 7\)

\(\displaystyle 2\)

\(\displaystyle 12\)

\(\displaystyle 5\)

Correct answer:

\(\displaystyle 7\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides. In this kite the two adjacent sides which are congruent are those at the top of the kite and then likewise, the two that are connected at the bottom of the kite.

Thus, \(\displaystyle a\) must equal \(\displaystyle 7\)

Example Question #23 : Kites

A kite has one set of equivalent sides each with a measurement of \(\displaystyle 9\). Additionally, the kite has a perimeter of \(\displaystyle 48.\) Find the length for one of the other two sides of the kite. 

Possible Answers:

\(\displaystyle 9\)

\(\displaystyle 15\)

\(\displaystyle 14\)

\(\displaystyle 13\)

\(\displaystyle 16\)

Correct answer:

\(\displaystyle 15\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

Therefore plug in the given information into the formula: 

\(\displaystyle perimeter=2(a+b)\), where \(\displaystyle a\) and \(\displaystyle b\) are the lengths of opposite sides of the kite and solve for \(\displaystyle b\)

\(\displaystyle 48=2(9+b)\)

\(\displaystyle \frac{48}{2}=(9+b)\)

\(\displaystyle 24=9+b\)

\(\displaystyle b=24-9=15\)

Example Question #24 : Kites

A kite has one set of equivalent sides each with a measurement of \(\displaystyle 31\). Additionally, the kite has a perimeter of \(\displaystyle 88.\) Find the length for one of the other two sides of the kite.

Possible Answers:

\(\displaystyle 16\)

\(\displaystyle 8\)

\(\displaystyle 11\)

\(\displaystyle 13\)

\(\displaystyle 18\)

Correct answer:

\(\displaystyle 13\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

Therefore plug in the given information into the formula: 

\(\displaystyle perimeter=2(a+b)\), where \(\displaystyle a\) and \(\displaystyle b\) are the lengths of opposite sides of the kite and solve for \(\displaystyle a\)

\(\displaystyle 88=2(a+31)\)

\(\displaystyle a+31=\frac{88}{2}\)

\(\displaystyle a=44-31=13\)

Example Question #25 : Kites

A kite has one set of equivalent sides each with a measurement of \(\displaystyle 94\) cm. Additionally, the kite has a perimeter of \(\displaystyle 450\) cm. Find the length for one of the other two sides of the kite.

Possible Answers:

\(\displaystyle 133in\)

\(\displaystyle 262cm\)

\(\displaystyle 231cm\) 

\(\displaystyle 131cm\) 

\(\displaystyle 133cm\) 

Correct answer:

\(\displaystyle 131cm\) 

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

Therefore plug in the given information into the formula: 

\(\displaystyle perimeter=2(a+b)\), where \(\displaystyle a\) and \(\displaystyle b\) are the lengths of opposite sides of the kite and solve for \(\displaystyle b\)

\(\displaystyle 450=2(94+b)\)

\(\displaystyle \frac{450}{2}=94+b\)

\(\displaystyle 225=94+b\)

\(\displaystyle b=225-94=131\)

Example Question #26 : Kites

A kite has one set of equivalent sides each with a measurement of \(\displaystyle \frac{2}{4}\) foot. Additionally, the kite has a perimeter of \(\displaystyle 4.5\) feet. Find the length for one of the other two sides of the kite. 

Possible Answers:

\(\displaystyle 0.5foot\)

\(\displaystyle 1.75 feet\)

\(\displaystyle \frac{3}{4} foot\)

\(\displaystyle 1.25 feet\)

\(\displaystyle 2.25 feet\)

Correct answer:

\(\displaystyle 1.75 feet\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

Therefore plug in the given information into the formula: \(\displaystyle perimeter=2(a+b)\), where \(\displaystyle a\) and \(\displaystyle b\) are the lengths of opposite sides of the kite and solve for \(\displaystyle b\).


\(\displaystyle 4.5=2(0.5+b)\)

\(\displaystyle 0.5+b=\frac{4.5}{2}=2.25\)

\(\displaystyle b=2.25-0.5=1.75\)

Example Question #331 : Plane Geometry

Kite_series_2

Using the kite shown above, find the length of side \(\displaystyle a\)

Possible Answers:

\(\displaystyle 8.5in\)

\(\displaystyle 5 in\)

\(\displaystyle 8in\)

\(\displaystyle 5.5 in\)

\(\displaystyle 16 in\)

Correct answer:

\(\displaystyle 5.5 in\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

Therefore plug in the given information into the formula: \(\displaystyle perimeter=2(a+b)\), where \(\displaystyle a\) and \(\displaystyle b\) are the lengths of opposite sides of the kite and solve for \(\displaystyle a\)

\(\displaystyle 43=2(a+16)\)

\(\displaystyle a+16=\frac{43}{2}\)

\(\displaystyle a+16=21.5\)

\(\displaystyle a=21.5-16=5.5\)


Example Question #28 : Kites

Kite_series_2

Using the kite shown above, find the length of side \(\displaystyle b.\)

Possible Answers:

\(\displaystyle 16in\)

\(\displaystyle 14in\)

\(\displaystyle 5.5in\)

\(\displaystyle 9in\)

\(\displaystyle 13.5in\)

Correct answer:

\(\displaystyle 16in\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

In this particular case the top sides that are connected at the top are congruent and the two sides that are connected at the bottom are congruent.

Thus, side \(\displaystyle b\) must equal \(\displaystyle 16\) inches. 


Example Question #29 : Kites

A kite has one set of equivalent sides each with a measurement of \(\displaystyle 9.5\). Additionally, the kite has a perimeter of \(\displaystyle 26.\) Find the length for one of the other two sides of the kite. 

Possible Answers:

\(\displaystyle 9\)

\(\displaystyle 3\)

\(\displaystyle 3.5\)

\(\displaystyle 5.5\)

\(\displaystyle 9.5\)

Correct answer:

\(\displaystyle 3.5\)

Explanation:

A kite is a geometric shape that has two sets of equivalent adjacent sides.

Therefore plug in the given information into the formula: 

\(\displaystyle perimeter=2(a+b)\), where \(\displaystyle a\) and \(\displaystyle b\) are the lengths of opposite sides of the kite and solve for \(\displaystyle b\)

\(\displaystyle 26=2(9.5+b)\)

\(\displaystyle 9.5+b=\frac{26}{2}\)

\(\displaystyle 9.5+b=13\)

\(\displaystyle b=13-9.5=3.5\)
