What is the sum of the interior angles in a triangle?
120 degrees
360 degrees
180 degrees
90 degrees
If one angle in a triangle is 50 degrees and another is 60 degrees, what is the third angle?
70 degrees
80 degrees
100 degrees
90 degrees
How do you calculate the exterior angle of a triangle?
Exterior angle = Interior angle 1 + 90°
Exterior angle = Interior angle 1 + Interior angle 2
Exterior angle = Interior angle 1 - Interior angle 2
Exterior angle = 180° - Interior angle 1
What is the measure of an exterior angle if the interior angle is 120 degrees?
60 degrees
150 degrees
30 degrees
90 degrees

10
6
8
4
What is the sum of the interior angles of a quadrilateral?
360 degrees
180 degrees
270 degrees
90 degrees
If a triangle has angles measuring 30 degrees and 70 degrees, what is the measure of the third angle?
80 degrees
70 degrees
90 degrees
60 degrees
What is the relationship between the interior and exterior angles of a polygon?
Exterior angles are equal to the sum of the interior angles.
Interior angles and exterior angles are complementary.
Interior angles and exterior angles of a polygon are supplementary.
Interior angles are always greater than exterior angles.
How many sides does a decagon have?
10
6
8
12

Pentagon
If a polygon has 12 sides, what is it called?
pentagon
octagon
hexadecagon
dodecagon
What is the measure of an exterior angle of a regular octagon?
45 degrees
90 degrees
60 degrees
30 degrees
How do you find the sum of the interior angles of a polygon with n sides?
(n - 1) * 180 degrees
(n + 2) * 90 degrees
(n - 2) * 180 degrees
n * 180 degrees
