properties of angles vocab

Question 1

transversal

Answer 1

a line that intersects the pair of parallel lines

Question 2

corresponding angles (F pattern)

Answer 2

one interior angle and one exterior angle that are non-adjacent (not touching) and on the same side of a transversal

Question 3

interior angles

Answer 3

any angles formed by a transversal and two parallel lines that lie inside the parallel lines

Question 4

exterior angles

Answer 4

any angles formed by a transversal and two parallel lines that lie outside the parallel lines

Question 5

vertically opposite angles (X pattern)

Answer 5

two angles that are opposite to one another with intersecting

Question 6

alternate interior angles (Z pattern)

Answer 6

two non-adjacent (not touching) interior angles on opposite sides of a transversal

Question 7

alternate exterior angles

Answer 7

two exterior angles formed between two lines and a transversal, on opposite sides of the transversal

Question 8

C pattern

Answer 8

two interior angles on the same side of the transversal that adds up to 180

Question 9

supplementary angles

Answer 9

two angles that add to 180
