Classify the triangle by its sides. the lengths of the sides are 9,9 and 9

it is an equilateral triangle

Step-by-step explanation:

Since all the sides are the same length, it is an equilateral triangle

If only two sides were the same length it would be isosceles

If they were all difference lengths, it would be scalene.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
