Parallel lines, proofs, and constructions

Front

What is the Converse of Corresponding Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

How can you show that two lines are parallel when cut by a transversal?

Back

Show that the corresponding angles are congruent.

Front

What is the Transitive Property in mathematics?

Back

If A = B and B = C, then A = C.

Front

What is the Corresponding Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

What are vertical angles?

Back

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

Front

What is the Alternate Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent.

Front

What is the Same Side Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of same-side interior angles is supplementary.

Front

What does it mean for lines to be perpendicular?

Back

Perpendicular lines intersect at a right angle (90 degrees).

Front

What is the Reflexive Property?

Back

For any number A, A = A.

Front

What is the Symmetric Property?

Back

If A = B, then B = A.
