Transversal Angle Relationships

Front

What is the relationship of vertical angles?

Back

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

Front

Define Alternate Interior Angles.

Back

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

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal. They are equal.

Front

Explain Same-Side Interior Angles.

Back

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

Front

What is the relationship of Alternate Exterior Angles?

Back

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

Front

How do you identify Vertical Angles in a diagram?

Back

Vertical angles are formed by the intersection of two lines and are located opposite each other.

Front

What is the sum of Same-Side Interior Angles?

Back

The sum of same-side interior angles is always 180 degrees.

Front

Define Transversal in geometry.

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the relationship between Alternate Interior Angles when lines are parallel?

Back

When two lines are parallel, alternate interior angles are equal.

Front

How can you prove that Corresponding Angles are equal?

Back

If two parallel lines are cut by a transversal, then the corresponding angles are equal.
