Question

can some help write a two colum proofs (geometry ) picture in the comments

Answer 1

there is only one and def not the answer you have to prove they are congruent

Answer 2

ok so since a triangle has to add up to 180 and you know that a right angle is 90 do 180-90 which is 90 then divide it by 2 so 90 divided by 2=45 so do 45+45+90=180

Answer 3

then do the same think for the other triangle and see if you get the same answer which I know you will
