Math 3 Unit 9 Review

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie on the same side of a transversal and between two parallel lines. They are supplementary, meaning they add up to 180°.

Front

What are linear pairs?

Back

Linear pairs are two adjacent angles formed when two lines intersect. The angles in a linear pair are supplementary, meaning they add up to 180°.

Front

Find the value of x if x + 95 = 180.

Back

x = 85

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180°.

Front

Find m∠D if m∠D + 116° = 180°.

Back

m∠D = 64°

Front

Which equation is correct to solve for x? 12X - 29 + 4X + 1 = 180.

Back

This equation can be solved to find the value of x.

Front

Find the missing length if the total length is 25 and one part is 10.

Back

The missing length is 15.

Front

What is the sum of angles in a triangle?

Back

The sum of angles in a triangle is always 180°.

Front

If two angles are complementary, what is their sum?

Back

The sum of complementary angles is 90°.

Front

What is the relationship between vertical angles?

Back

Vertical angles are equal to each other when two lines intersect.
