The angle formed by the equal sides of an isosceles triangle is 100°. The other side has measure 45.0 cm. How long are the equal sides?

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
