Example Questions
Example Question #91 : Geometry
Which is the greater quantity?
(a) The area of a regular hexagon with sidelength 1
(b) The area of an equilateral triangle with sidelength 2
(a) and (b) are equal
(b) is greater
It is impossible to tell from the information given
(a) is greater
(a) is greater
A regular hexagon with sidelength can be seen as a composite of six equilateral triangles, each with sidelength . Since area is in direct proportion to the square of the sidelength, the area of the equilateral triangle with sidelength is equal to that of four of those triangles. This makes the hexagon greater in area, and it makes (a) the greater quantity.
Example Question #92 : Geometry
Which is the greater quantity?
(a) The perimeter of a regular pentagon with sidelength 1 foot
(b) The perimeter of a regular hexagon with sidelength 10 inches
It is impossible to tell from the information given.
(b) is greater.
(a) is greater.
(a) and (b) are equal.
(a) and (b) are equal.
The sides of a regular polygon are congruent, so in each case, multiply the sidelength by the number of sides to get the perimeter.
(a) Since one foot equals twelve inches, inches.
(b) Multiply: inches
The two polygons have the same perimeter.
Example Question #93 : Geometry
A hexagon has six angles with measures
Which quantity is greater?
(a)
(b) 240
It is impossible to tell from the information given
(b) is greater
(a) is greater
(a) and (b) are equal
(a) and (b) are equal
The angles of a hexagon measure a total of . From the information, we know that:
The quantities are equal.
Example Question #96 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
A hexagon has six angles with measures
Which quantity is greater?
(a)
(b)
It is impossible to tell from the information given.
(a) is greater.
(a) and (b) are equal.
(b) is greater.
(b) is greater.
The angles of a hexagon measure a total of . From the information, we know that:
This makes (b) greater.
Example Question #97 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
The angles of Hexagon A measure
The angles of Octagon B measure
Which is the greater quantity?
(A)
(B)
(B) is greater
It is impossible to determine which is greater from the information given
(A) is greater
(A) and (B) are equal
(B) is greater
The sum of the measures of a hexagon is . Therefore,
The sum of the measures of an octagon is . Therefore,
, so (B) is greater.
Example Question #98 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
The angles of Pentagon A measure
The angles of Hexagon B measure
Which is the greater quantity?
(A)
(B)
(B) is greater
It is impossible to determine which is greater from the information given
(A) and (B) are equal
(A) is greater
(A) is greater
The sum of the measures of the angles of a pentagon is . Therefore,
The sum of the measures of a hexagon is . Therefore,
, so (A) is greater.
Example Question #7 : Hexagons
A regular hexagon has the same perimeter as the above right triangle. What is the length of one side of the hexagon?
The length cannot be determined from the information given.
By the Pythagorean Theorem, the hypotenuse of the right triangle is
inches, making its perimeter
inches.
The regular hexagon, which has six sides of equal length, has the same perimeter, so each side measures
inches.
Example Question #101 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
A regular hexagon has the same perimeter as the above right triangle. What is the length of one side of the hexagon?
The length cannot be determined from the information given.
By the Pythagorean Theorem, the hypotenuse of the right triangle is
inches, making its perimeter
inches.
The regular hexagon, which has six sides of equal length, has the same perimeter, so each side measures
inches.
