3.4

Question 1

Thm 3.3

Answer 1

If two lines are perpendicular then they intersect to form four right angles.

Question 2

Thm 3.4

Answer 2

All right angles are congruent

Question 3

Thm 3.5

Answer 3

If two lines intersect to form a pair of adjacent congruent angles, then the lines are perpendicular

Question 4

Transversal

Answer 4

A line that intersects two or more coplanar lines at different points

Question 5

Corresponding angles

Answer 5

Two angles are are corresponding angles if they occupy corresponding positions

Question 6

Alternate interior angles

Answer 6

Two angles are alternate interior angles if they lie between l and m on opposite sides of t

Question 7

Alternate exterior angles

Answer 7

Two angles are alternate exterior angles if they lie outside l and m on opposite sides of t

Question 8

Consecutive interior angles

Answer 8

Two angles are consecutive interior angles if they lie between l and m on opposite sides of t

Question 9

Corresponding angles postulate

Answer 9

If two parallel lines are cut by a transversal then the pairs of corresponding angles are congruent.

Question 10

Alternate interior angles theorem

Answer 10

If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent

Question 11

Consecutive interior angles thm

Answer 11

If two parallel lines are cut by a transversal then the pairs of alternate exterior angles are congruent

Question 12

Alternate exterior angles thm

Answer 12

If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent

Question 13

Perpendicular transversal thm

Answer 13

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

Question 14

Corresponding angles converse

Answer 14

If two lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel
