Triangle abc has vertices at a(−1 , 2), b(4, 2), and c(3, −1). classify the triangle according to the side lengths. a) equilateral b) isosceles c) right d) scalene

B) Isosceles

Step-by-step explanation:

The given triangle has vertices at A(-1,2), B(4,2) and C(3,-1).

We must first determine the length of the sides of the triangle, before we can classify it.

We apply the distance formula to find length of the sides.

.

The length of side BC

The length of side AC

We simplify to obtain;

Since , the given triangle is an isosceles triangle.

The correct answer is

7,24
