Question

For an indirect proof, what must first be assumed to prove that LaTeX: \angle X∠ Xis a right angle?

Answer 1

Answer:

If the lines that forms < X are perpendicular, it can be assumed that it is a right angle.

Step-by-step explanation:

An indirect proof of an angle is an assumption about the value of the angle that can be made by mere inspection and some considerations.

                                     < X = right angle =  $90^{o}$

A right angle is one that is equal to $90^{o}$. As an indirect proof, if the lines that forms the angle are perpendicular; then it can be assumed to be a right angle. Because perpendicular lines are at right angle to one another.
