Question

Can someone help me write an indirect proof for the following:

The two non-right angles of a right triangle measure less than 90 degrees.

I could still not understand how to write indirect proofs.

Answer 1

Indirect Proof:

Answer 2

So when I write an Indirect proof it is written like:

Assuming that two non right angles of a right triangle measure less than 90 degrees, this is not true because the two right triangles are 90 degrees and it would equal 180 degrees in total.
