Question

Help!! will give medals :)
Given:∠1≅∠2 Prove:m∠3+m∠4=90
Statements Reason
1)∠1≅∠2 Given
2)??????? ???????
3)????? ??????
4)m∠3+m∠4=90 ?????

Answer 1

i think 2 is l is perpendicular to m
3 is angle 3 is congruent to angle 4 by theorem 3.10
4 is definition of complementarty angles

Answer 3

@Loser66 @GoldPhenoix

Answer 4

So you ask questions too.

Answer 5

To prove.

Answer 6

Based on what's given, it's impossible to prove it

Answer 7

@FutureMathProfessor Actually, it is. Look at the picture.

Answer 8

No it's not

Answer 9

If a1 = a2, then a1 + a2 = 180 = 2(a1) = 180. a1 = a2 = 90
Then a5 can only be 90 because the line is a perpend, leaving the rest to be 360-(90+180). So a3 and a4 share 90.

Answer 10

One cannot justify If a1 = a2, then a1 + a2 = 180

Answer 11

@FutureMathProfessor Ever heard of "sum of angles on a straight line = 180?"

Answer 12

One does not know that the line is straight

Answer 13

@primeralph could you help me explain it in that format

Answer 14

Very poorly written problem in my opinion

Answer 15

@FutureMathProfessor Go home, you're drunk.
