8th- Transversal Angles

Front

What are transversal angles?

Back

Transversal angles are angles formed when a transversal intersects two or more lines. They include corresponding angles, alternate interior angles, and alternate exterior angles.

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°.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines. They are equal when the lines are parallel.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

Front

What are alternate exterior angles?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

The corresponding angles are equal.

Front

If ∠A = 75°, what is the measure of the corresponding angle when two parallel lines are cut by a transversal?

Back

The corresponding angle is also 75°.

Front

If ∠B and ∠C are alternate interior angles and ∠B = 130°, what is the measure of ∠C?

Back

∠C = 130°.

Front

What is the relationship between the sum of the angles formed by a transversal and the lines it intersects?

Back

The sum of the angles on the same side of the transversal is supplementary, meaning they add up to 180°.

Front

If ∠D = 45° and is an exterior angle, what is the measure of the alternate exterior angle?

Back

The alternate exterior angle is also 45°.
