Geometry Unit 4 Proofs Using Congruence Review

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal.

Front

Identify the relationship of angles formed by a transversal intersecting two parallel lines.

Back

The angles can be classified as corresponding angles, same side interior angles, alternate interior angles, or alternate exterior angles.

Front

What is the measure of angle 8 if angle 1 is 41°?

Back

Angle 8 is also 41° because they are alternate exterior angles.

Front

If quadrilateral MNOP is congruent to quadrilateral TSVU, what can we say about their corresponding sides?

Back

The corresponding sides of congruent quadrilaterals are equal in length.

Front

What is the length of \( \overline{TU} \) if quadrilateral MNOP is congruent to quadrilateral TSVU and \( \overline{SV} = 51 \) km?

Back

The length of \( \overline{TU} \) is 51 km.

Front

Find the value of X if the angles are supplementary and one angle measures 120°.

Back

X = 60° because supplementary angles add up to 180°.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal.

Front

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

Back

The sum of the interior angles of a quadrilateral is 360°.

Front

If two angles are alternate interior angles, what can we conclude if they are equal?

Back

If two alternate interior angles are equal, the lines cut by the transversal are parallel.

Front

What is the definition of congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size.
