Transversals and Angles of Triangles

Front

What are congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If angle Q and angle B are congruent, what can we say about their measures?

Back

The measures of angle Q and angle B are equal.

Front

What is the value of angle C if angle A is 74 degrees and they are supplementary?

Back

Angle C is 106 degrees.

Front

What is the relationship between alternate interior angles when a transversal crosses two parallel lines?

Back

Alternate interior angles are congruent.

Front

What is the measure of angle 1 if angle 8 is 50 degrees?

Back

Angle 1 is also 50 degrees because they are congruent.

Front

If angle 4 and angle 6 are supplementary, and angle 4 is 36 degrees, what is the measure of angle 6?

Back

Angle 6 is 144 degrees.

Front

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

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

If angle 2 is 70 degrees, what is the measure of angle 5 if they are corresponding angles?

Back

Angle 5 is also 70 degrees.

Front

What is the value of x if angle 3 is 40 degrees and angle x is supplementary to angle 3?

Back

x is 140 degrees.
