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.

Front

Define supplementary angles.

Back

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

Front

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.

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.

Front

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.

Front

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

Back

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

Front

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).

Front

What is the relationship between vertical angles?

Back

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

Front

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).

Front

What is the sum of the measures of angles on a straight line?

Back

The sum of the measures of angles on a straight line is 180 degrees.
