Answer 2

I got C is that right

Answer 3

@ganeshie8

Answer 4

@phi

Answer 5

Its b because both angle pairs are corresponding

Answer 6

Thanks @ganeshie8

Answer 7

thx

Answer 8

your welcom

Answer 9

can i ask one more questions please

Answer 10

sure

Answer 11

Are the following figures similar?

Answer 12

No; the corresponding angles are not congruent.

No; the corresponding sides are not proportional.

Yes; the corresponding angles are congruent.

Yes; the corresponding sides are proportional.

Answer 13

i did 136+44=180 that means its yes

Answer 14

A. in order for them to be similar the angles have to be congruent.

Answer 15

isnt it C

Answer 16

No A

Answer 17

oh how can u expalin

Answer 18

it equals 180 though

Answer 19

just like this one here

Answer 20

Yes; they have proportional corresponding sides.

No; they do not have proportional corresponding sides.

Yes; they have congruent corresponding angles.

No; they do not have congruent corresponding angles.

Answer 21

This one is C because the angles are congruent.

Answer 22

b/c there is 2 105's?

Answer 23

can i ask the very last question please

Answer 24
