Question

If m∠1+m∠2=90 and m∠2=m∠3 then m∠1=m∠3=90
What property is this

Answer 1

ummm U think that this is a little wrong

it should just finish m<1 + m< 3 = 90

Answer 2

This is the same question that was asked here:

http://openstudy.com/study#/updates/508e0e1ee4b078e4677b70ca

...Where I provided a proof as to why this question does not make sense.

Answer 3

What does the answer say?

Answer 4

well lets look at it this way

let m<1 = 70, then m<2 = 20 m<1 + m<2 = 90 true... as written

then m<2 = m< 3 so m<2 = 20... so m<3 = 20

and your last statement is

m<1 = m<3 = 90........ m<1 = 70 and m<3 = 20... there are not equal and don't equal 90.

so there appears a typo...

Answer 5

what?

Answer 6

Okay here I will type it out one more time and will double check it before I post it and tell me if I changed something then

Answer 7

If
M∠1+M∠2=90
and
M∠2=M∠3
then
M∠1+M∠3=90

Answer 8

see how thats different to your posted question.

Answer 9

I just don't see how a + and a = can really change the property of it but I guess thats why Im asking the question and your the one answering them...Thanks for your time anyway and I will admit yes I did have one little typo and as I said before I apologize for sounding a little rude but I was really frustrated as it is.
