Question

Use a paragraph proof to prove the corresponding angles postulate:

Given: segment A B is parallel to segment C D.

Prove: Corresponding angles are congruent

Answer 1

Draw a line to the left of this stuff, perpendicular to AB. Because AB and CD parallel, the line is also perpendicular to CD. So now we have created a quadrilateral with angles 90 degrees, 90 degrees, angle #4, and angle #5.

Answer 2

@anas2000 and @BAdhi can you please help me on this ?

Answer 3

I just did

Answer 4

do I write that ?

Answer 5

what do u mean do i right it

Answer 6

I have to explain it in a box

Answer 7

?????

Answer 8

An alternative explanation:

A1 = A3 (vert oppo angles)
A3 = A5 (alt angles equal, AB // CD)
i.e A1 = A5
i.e corr angles equal

Answer 9

You can show what you've worked out so far
