Answer 1

Write an indirect proof proving the two non-right angles of a right triangle measure less than 90°.

Answer 2

what is an indirect proof?

Answer 3

That is indirect.

Answer 4

we don't have any concrete value of angles, that is indirect proof

Answer 5

if I say A =40, B = 50
that is direct

Answer 6

hi!
actually an indirect proof means something like a proof by contradiction

Answer 7

:)

Answer 8

you might assume that the sum of the two angles is larger than 90, and arrive a a simple contradiction

Answer 9

the contradiction would be what @OOOPS wrote above, the sum of the three angles would then be larger than 180 degrees, and that is the contradiction
