geometry semester exam

Front

What is the Side-Side-Side (SSS) Congruence Postulate?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the Division Property of Equality?

Back

If a = b, then a/c = b/c for any non-zero c.

Front

What are Adjacent Angles?

Back

Two angles that share a common vertex and a common side but do not overlap.

Front

In a 30-60-90 triangle, what is the ratio of the lengths of the sides?

Back

1 : √3 : 2, where 1 is the length of the side opposite the 30° angle.

Front

What is the Symmetric Property of Equality?

Back

If a = b, then b = a.

Front

What are Vertical Angles?

Back

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

Front

What is the Angle-Side-Angle (ASA) Congruence Postulate?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the Addition Property of Equality?

Back

If a = b, then a + c = b + c for any c.

Front

What are Complementary Angles?

Back

Two angles whose measures add up to 90 degrees.

Front

What are Supplementary Angles?

Back

Two angles whose measures add up to 180 degrees.
