HELP WITH GEOMETRY PROOFS PLEASE!!!! Thanks?

Question

Given: angle 4. is an exterior angle of the triangle
Prove: angle 4 = measure of angle 1 plus the measure of angle 2.

Two column proof:
Statement 1 says angle 4 is an exterior angle of the triangle. Reason 1 says “given”.
Statement 2 says the measures of angles 1, 2 and 3 added together equal 180 degrees.
Reason 2 says ?
Statement 3 says angles 3 and 4 are a linear pair.”
Reason 3 says?
Statement 4 says angles 3 and 4 are supplementary angles.
Reason 4 says “If two angles form a linear pair, then they are supplementary.”
Statement 5 says measure of angle 3 plus the measure of angle 4 equals 180 degrees.
Reason 5 says ?
Statement 6 says the sum of angles 1, 2 and 3 equal the sum of angle 3 and 4.”
Reason 6 says?
Statement 7 says measure of angles 1 and 2 equal the measure of angle 4
Reason 7?

Answer 1

All these are in your text book. Look them up.

Answer 2

It's hard for me to do without seeing a picture. When I had math problems I would go to http://mathforum.org/drmath/ It's free, but you won't get an answer until possibly tomorrow afternoon. Sorry I couldn't help. Good luck.

Answer 3

evaluate 2 good perspective triangles EAB and DCB the place EA = AB AB = BC perspective A = perspective C = ninety ranges and likewise perspective EBA = perspective DBC (opposite angles) If 2 triangles have 2 components and a pair of of the angles are additionally equivalent then the triangles are comparable for this reason perspective E = perspective D <= answer

Answer 4

this question is very difficult to answer without a diagram or drawing of some sort. I would know exactly what the answers, but i cant tell you becuase i don't have a diagram.

Sorry!

Answer 5

ewww proofs... i feel your pain man!! i hate PROOFS!!
