Help With Geometry

If someone could help me out with these proofs, I would really appreciate it.... I'm horrible at them :unsure:

 

haha doing the same thing man, and i have no clue either

 

---- geometry. lol.

not into that stuff yet, just got into like "If Then" statements.

 

Hmm, I did Geometry 2 years ago, so I forget some things, but proofs are teh lame lol

but for the first

It would be perpendicular because if if angle 3=4, 1=2 should be congruent as well, meaning each angle is 45 degrees, making each side 90 degrees which is equivalent to a right angle, and the line coming straight down is perpendicular because of that: it makes right angles on both sides.

the second

2=3 because they're both 45 degree angles, since cd is perpendicular, means angles 1 and 2 are 45.

the third

angle 2= 180- 1(since they make a straight line which is 180 degrees), and since it said that angle 1 is the same as angle 3, angle 2= 180-3 for it to be supplemantary (meaning congruent to 180)

hope that helps

 

i know how to do numba 1 but i dont hve time to type it out now sorri

 

statement and reason. ready set go

 

Did you sign-up just to ask this?

Anyway, I dunno. I had Geometry 4 years ago and never understood proofs or w/e they are.

 

proofs = where geometry kills me

We're basically starting proofs, but damn, they're so annoying.

Sorry, I'd help but we just started them damn things. Go normal math instead of advanced like I was last year.
