Missing Angles and Angle Relationships

Front

What is the definition of 'congruent' in geometry?

Back

Congruent means equal in size and shape.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

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

If two angles are complementary, what is the sum of their measures?

Back

The sum of the measures of two complementary angles is 90 degrees.

Front

If two angles are supplementary, what is the sum of their measures?

Back

The sum of the measures of two supplementary angles is 180 degrees.

Front

Solve for angle 2 if angle 1 is 55 degrees and they are supplementary.

Back

Angle 2 = 125 degrees.

Front

Solve for angle 5 if angle 4 is 120 degrees and they are vertical angles.

Back

Angle 5 = 120 degrees.

Front

What is the relationship between angles formed by two parallel lines cut by a transversal?

Back

The angles formed have specific relationships: corresponding angles are equal, alternate interior angles are equal, and same-side interior angles are supplementary.

Front

Identify the pair of angles that are alternate interior angles: angle 3 and angle 5, or angle 1 and angle 7?

Back

Angle 3 and angle 5 are alternate interior angles.

Front

What is the measure of angle 6 if angle 5 is 35 degrees and they are corresponding angles?

Back

Angle 6 = 35 degrees.
