If a = (8, 2) b = (11, 13) and c = (2, 6), classify the the following triangle as either right or isosceles

isosceles

Step-by-step explanation:

I took the quiz and got the question correct. I promise isosceles is the correct answer.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
