Answer 2

Does this sound right? It is given that transversal t intersects parallel lines PQ and RS. You know angle 1 and angle 4 equal 180 using the definition of supplementary angles. Angle 5 and angle 8 equal 180 using the definition of supplementary angles. Angle 1 and angle five are the same measure using the corresponding angles postulate. Therefore, angle 4 and angle 8 are of equal measure.

Answer 3

yes i think this so sounds really convincing :))

Answer 4

good job

Answer 5

Are the postulates and theorems used correct?

Answer 6

yeah i will check just give me a minute

Answer 8

yeah u r right

Answer 9

Thank you so much!

Answer 10

just add therefore the corresponding angles 4 and 8 are equal

Answer 11
