Geometry Review

Front

What is the measure of the missing angle if one angle is 108 degrees?

Back

72 degrees (since angles in a triangle sum to 180 degrees).

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always congruent.

Front

Solve for k: 4k + 24 = 6k - 10

Back

k = 17.

Front

If two angles are supplementary and one angle measures 110 degrees, what is the measure of the other angle?

Back

70 degrees (180 - 110 = 70).

Front

What is the sum of the interior angles of a triangle?

Back

180 degrees.

Front

What is an angle bisector?

Back

A line that divides an angle into two equal parts.

Front

What is the definition of an acute angle?

Back

An angle that measures less than 90 degrees.

Front

What is the definition of an obtuse angle?

Back

An angle that measures more than 90 degrees but less than 180 degrees.
