Question

given: AC||BD, and AB||CD
Prove: 10 years ago

Answer 1

A) <PQC and <ACP are supplementary by the Linear Pair Theorem
B) For parallel lines cut by a transversal, corresponding angles are congruent, so \[<ABC \approx<PCQ\]
C)\[<OCP \approx<BCD\] by the vertical angle theorem
D)For parallel lines cut by a transversal, corresponding angles are congruent, so \[ <OCP \approx<ABC\]
E) For parellel lines cut by a transversal, corresponding angles are congruent, so \[<OCA \approx<CBD\]

Answer 2

got it?

Answer 3

no i dont v.v

Answer 4

@dan815

Answer 5

:(

Answer 6

tooo much to read

Answer 7

:( im sorry you dont gotta help

Answer 8

Id help, but I suck at proofs

Answer 9

its alright know anyone who is good at it?

Answer 10

id go with c

Answer 11

thanks :3

Answer 12

np anytime

Answer 13

the step right after the missing one says..
By the definition of congruent angle, m<OCP = m<ABC

the missing congruency is probably relating those two angles

Answer 14

so what does that mean?

Answer 15

It is not stated in the proof yet that OCP is congruent to ABC, that is the missing step, they are corresponding angles

C is true, but does not follow the proof

Answer 16

so its not the right answer? sorry im kinda getting confused

Answer 17

, D is the one

Answer 18

Ohh well thanks :3

Answer 19

welcome
