Unit 6 Lesson 7: Parallelogram Proofs

Question 1

alternate interior angles

Answer 1

the two sets of two angles located inside two parallel lines that are crossed by a transversal; the angles located diagonally across the transversal are equal to each other

Question 2

ASA Congruence Theorem –

Answer 2

– the theorem stating that if two triangles have one pair of congruent sides between two pairs of congruent angles, then the triangles are congruent

Question 2

Alternate Interior Angles Theorem

Answer 2

the theorem that states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent

Question 3

corresponding angles

Answer 3

the two angles located on the same side of the transversal and in the same corresponding position in the group of four corners created by both intersections

Question 4

Corresponding Angles Postulate

Answer 4

the postulate that states that if two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent

Question 5

parallelogram

Answer 5

a quadrilateral with opposite sides parallel and equal

Question 6

straight angle

Answer 6

an angle whose sides lie in opposite directions from the vertex in the same straight line and which equals two right angles
