Unit 5/4/3 Review

Front

Find y if y + 2 = 6.

Back

4

Front

What additional information is required to prove the two triangles are congruent by ASA?

Back

The length of one side of the triangle.

Front

Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar: Triangle A has angles 30°, 60°, and 90°; Triangle B has angles 30°, 60°, and 90°.

Back

AA

Front

Find the measure of the indicated angle if the triangle has angles 30°, 60°, and ?.

Back

90

Front

Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar: Triangle A has sides 3, 4, 5; Triangle B has sides 6, 8, 10.

Back

SSS

Front

What is the definition of congruent triangles?

Back

Triangles that are identical in shape and size.

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, the triangles are congruent.

Front

What is the Side-Angle-Side (SAS) congruence postulate?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the Side-Side-Side (SSS) congruence postulate?

Back

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

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but may differ in size.
