Qzz: Review 4.1-4.3

Front

Which postulate can we use to prove the two triangles are congruent?

Back

SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

If 2 of the angles of a triangle are 30 and 70 degrees, the third angle measures...

Back

80 degrees. The sum of angles in a triangle is always 180 degrees.

Front

What is an 'Acute' Angle?

Back

An angle that measures less than 90 degrees.

Front

Solve for x: 2x + 4 = 10

Back

x = 3.

Front

Which postulate can we use to prove the two triangles are congruent?

Back

SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

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

Back

180 degrees.

Front

Define 'Right Angle'.

Back

An angle that measures exactly 90 degrees.

Front

What is the definition of 'Complementary Angles'?

Back

Two angles that add up to 90 degrees.

Front

What is the definition of 'Supplementary Angles'?

Back

Two angles that add up to 180 degrees.

Front

If one angle measures 45 degrees, what is the measure of its complement?

Back

45 degrees.
