Question 1

transversal

Answer 1

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

Question 2

corresponding angles

Answer 2

2 angles are corresponding angles if they occupy corresponding positions,

Question 3

alternate interior angles

Answer 3

2 angles are alternate interior angles if they lie between (cursive) l and m on opposite sides of t.

Question 4

alternate exterior angles

Answer 4

2 angles are alternate exterior angles if they lie outside (cursive) l and m on opposite sides of t.

Question 5

consecutive interior angles

Answer 5

2 angles are consecutive interior angles if they lie between (cursive) l and m on the same side of t

Question 6

corresponding angles postulate

Answer 6

if 2 parallel lines are cut by transversal, then the pairs of corresponding angles are congruent

Question 7

alternate interior angles theorum

Answer 7

if 2 parallel lines are cut by a transversal, then the pairs of alt. int. angles are congruent.

Question 8

consecutive interior angles theorum

Answer 8

if two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary.

Question 9

alternate exterior angles theorum

Answer 9

if 2 parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.

Question 10

perpendicular transversal theorum

Answer 10

if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the second.
