Question

Find the lengths of the sides of the triangle, then click to identify the triangle as scalene, isosceles, or equilateral. K(7, 0), L(3, 4), M(2, -1)

Answer 1

triangle KLM is isosceles

Explanation:

`kl = \sqrt{(3 - 7) ^(2) + ({4 - 0) ^(2) } } = 4 √(2) \\ lm = \sqrt{(2 - 3 ) ^(2) + ( - 1 - 4) ^(2) } = √(26) \\ lk = \sqrt{(2 - 7) ^(2) + ( - 1 - 0) ^(2) = √(26) }`

therefore it is isosceles.
