Congruent vs Supplementary

Front

What are congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If angle A measures 50 degrees, what is the measure of its supplementary angle?

Back

130 degrees (180 - 50 = 130).

Front

If angle B measures 90 degrees, what is the measure of its supplementary angle?

Back

90 degrees (90 + 90 = 180).

Front

If angle C measures 120 degrees, what is the measure of its supplementary angle?

Back

60 degrees (180 - 120 = 60).

Front

If angle D measures 30 degrees, what is the measure of its supplementary angle?

Back

150 degrees (180 - 30 = 150).

Front

Which angles are congruent: angle 1 = 45 degrees, angle 2 = 45 degrees, angle 3 = 60 degrees?

Back

Angle 1 and angle 2 are congruent.

Front

If angle E is congruent to angle F, and angle E measures 75 degrees, what is the measure of angle F?

Back

75 degrees.

Front

What is the relationship between angle 2 and angle 5 if they are supplementary?

Back

Their measures add up to 180 degrees.

Front

What is the relationship between angle 2 and angle 6 if they are congruent?

Back

They have the same measure.
