Geometry Triangles & Congruence 4

Question 1

Two triangles have two pairs of equal angles and a pair of equal non-included sides. Which postulate proves congruence?

Accepted Answer

AAS

Answer

Angle-Angle-Side uses two angles and a non-included equal side.

Question 2

In a right triangle, the side opposite the right angle is called the:

Accepted Answer

Hypotenuse

Answer

The hypotenuse is the longest side, opposite the right angle.

Question 3

If two angles of one triangle equal two angles of another, the triangles are:

Accepted Answer

Similar

Answer

Two equal pairs of angles make triangles similar (AA), not necessarily congruent.

Question 4

A triangle has angles 90, 45, and 45 degrees. It is best described as:

Accepted Answer

Right isosceles

Answer

A 90-degree angle with two equal 45-degree angles is right and isosceles.

Question 5

What does CPCTC stand for in geometry proofs?

Accepted Answer

Corresponding Parts of Congruent Triangles are Congruent

Answer

CPCTC states corresponding parts of congruent triangles are congruent.
