Question

given: line RS is perpendicular to line ST, and TU is perpendicular to line ST, V is the midpoint of ST

Prove: Triangle RSV = triangle UTV


is it a hypotenuse leg?

Answer 1

>>is it a hypotenuse leg? No, because you do not know that the two hypotenuses are congruent.

Pick up the pair of vertical angles that are congruent (see attachment) and go with ASA Postulate when you write the proof.

Answer 2

Cab=n it be anything else? Because this is part of my like project and you could only use one of each thing (ASA, SAS, SSS, etc.) and i already used ASA?

Answer 3

can*

Answer 4

Do you have the LA Corollary or AAS Theorem as reasons you can use?

Answer 5

i also already used AAS and i don't know what LA corollary is (haven't learned that yet) :/

Answer 6

is their anyway for this to be SAS?

Answer 7

I see no way to get a second pair of congruent sides. So, I don't think SAS will work here.

LA Corollary (just in case you are wondering what it is)

Two right triangles are congruent if a leg and the adjacent acute angle of one are equal respectively to a leg and the adjacent acute angle of the other (L.A)

Answer 8

Maybe you could change one of your other proofs.

Answer 9

yeah i'll see what i can do :D thankyou for your help

Answer 10

You are welcome.
