Unit 2 Test Review

Front

What is the property of opposite angles in a parallelogram?

Back

Opposite angles in a parallelogram are congruent.

Front

If angle A in parallelogram ABCD measures 60 degrees, what is the measure of angle C?

Back

Angle C also measures 60 degrees.

Front

What are the properties of parallelograms regarding their sides?

Back

Opposite sides are parallel and congruent.

Front

What does the acronym SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, meaning all three corresponding sides are congruent.

Front

In an isosceles triangle, if one angle measures 65 degrees, how do you find the other angles?

Back

The two base angles are equal, so subtract 65 from 180 and divide by 2 to find each base angle.

Front

What is the Triangle Congruence Theorem SAS?

Back

SAS stands for Side-Angle-Side, where the angle is between two congruent corresponding sides.

Front

What happens to the angles of a triangle when one angle is known in an isosceles triangle?

Back

The two base angles are equal and can be calculated using the triangle sum theorem.

Front

What is the significance of the diagonals in a parallelogram?

Back

The diagonals of a parallelogram bisect each other.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

How does reflecting a triangle across a line affect its vertices?

Back

The vertices of the triangle will coincide with their corresponding points on the opposite side of the line.
