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 same-side interior angles.

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

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.

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie between two lines and on the same side of a transversal.

If angle 1 is 70°, what is the measure of angle 2 if they are supplementary?

Back

Angle 2 = 110° (because 70° + 110° = 180°).

If angle 3 is 45°, what is the measure of angle 4 if they are corresponding angles?

Back

Angle 4 = 45° (corresponding angles are equal).

What is the relationship between vertical angles?

Back

Vertical angles are equal; when two lines intersect, the angles opposite each other are equal.

If angle 5 is 60°, what is the measure of angle 6 if they are alternate interior angles?

Back

Angle 6 = 60° (alternate interior angles are equal).
