parallel lines cut by transversal flashcard

Front

What are vertical angles?

Back

Vertical angles are pairs of opposite angles formed by the intersection of two lines. They are always congruent.

Front

What are 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 congruent.

Front

What are adjacent angles?

Back

Adjacent angles are two angles that share a common vertex and a side but do not overlap.

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 congruent.

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. They are congruent.

Front

What are 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 a transversal. They are supplementary.

Front

What is the relationship of consecutive exterior angles?

Back

Consecutive exterior angles are pairs of angles that lie outside two parallel lines and on the same side of a transversal. They are supplementary.

Front

What is the sum of the angles around a point?

Back

The sum of the angles around a point is always 360 degrees.

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 degrees.

Front

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

Back

The alternate interior angles are congruent.
