Atriangle’s first angle measure is 72∘.
a triangle’s second angle measure is 44∘.
a triangle’s third angle measure is 64∘.

what triangle would this make?

An Acute triangle because none of the angels are above 90

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
