Example Questions
Example Question #1 : How To Find The Length Of A Side In Other Polygons
In a septagon, each of the sides are equal to one another. If the perimeter is
feet, what is the length of one of the sides?
If the perimeter of a septagon, in which each side is equal to the other, is 98, the length of each side will be 7 feet because 98 divided by 7 is 14.
Example Question #1 : Lines
Find the distance between and
.
To find the distance, first remember the distance formula: . Plug in so that you have:
. Simplify so that you get
. This yields
.
Example Question #1 : How To Find An Angle
Examine the above diagram. If , give
in terms of
.
The two marked angles are same-side exterior angles of parallel lines, which are supplementary - that is, their measures have sum 180. We can solve for in this equation:
Example Question #31 : Geometry
Examine the above diagram. If , give
in terms of
.
The two marked angles are same-side interior angles of parallel lines, which are supplementary - that is, their measures have sum 180. We can solve for in this equation:
Example Question #31 : Isee Upper Level (Grades 9 12) Mathematics Achievement
Examine the above diagram. What is ?
By angle addition,
Example Question #3 : Lines
Examine the above diagram. Which of the following statements must be true whether or not and
are parallel?
Four statements can be eliminated by the various parallel theorems and postulates. Congruence of alternate interior angles or corresponding angles forces the lines to be parallel, so
and
.
Also, if same-side interior angles or same-side exterior angles are supplementary, the lines are parallel, so
and
.
However, whether or not
since they are vertical angles, which are always congruent.
Example Question #251 : Geometry
and
are supplementary;
and
are complementary.
.
What is ?
Supplementary angles and complementary angles have measures totaling and
, respectively.
, so its supplement
has measure
, the complement of
, has measure
Example Question #2 : How To Find An Angle
Note: Figure NOT drawn to scale.
In the above figure, and
. Which of the following is equal to
?
and
form a linear pair, so their angle measures total
. Set up and solve the following equation:
Example Question #1 : How To Find An Angle
Two angles which form a linear pair have measures and
. Which is the lesser of the measures (or the common measure) of the two angles?
Two angles that form a linear pair are supplementary - that is, they have measures that total . Therefore, we set and solve for
in this equation:
The two angles have measure
and
is the lesser of the two measures and is the correct choice.
Example Question #2041 : Hspt Mathematics
Two vertical angles have measures and
. Which is the lesser of the measures (or the common measure) of the two angles?
Two vertical angles - angles which share a vertex and whose union is a pair of lines - have the same measure. Therefore, we set up and solve the equation
