Question

WILL MEDAL!!!
How does the slope formula prove that a triangle has a right angle?

Answer 1

It doesn't have parallel lines because it will never intercept, and the lines that make a triangle intercept each other. The lines are not congruent.

Answer 2

But how does the formula prove that?

Answer 3

you can eliminate parallel sides Parallel lines will never intercept, and the lines that make a triangle all intercept each other now after allll that we are down to only three choices, congruent sides, right angle, and congruent angles the formula (y=mx+b) three times to make the three different sides you will get the lengths of you triangles which can prove that the sides are congruent, congruent means equal If it is an equilateral triangle it would also prove that all the angles are congruent but it could also prove that the sides and angles are not all congruent, and that you end up with a right angle ;-;

Answer 4

buutttt to prove it is a right angle just so you will know simply is that you gotta prove that the sides and angles are not all congruent

Answer 5

that help what so ever?

Answer 6

Yes, thank you so much!!
