Question

whether points (3,3), (-4,-1) and (3, -5) are the vertices of an isosceles
triangle.​

Answer 1

Answer:

by distance formula

AB=root65

BC=root65

AC=8

two sides are equal so these points are vertices of isosceles triangle

Answer 2

Answer:

Yes , The given points are the vertices of isosceles triangle.

Step-by-step explanation:

By distance formula

AB= √(-4-3)²+(-1-3)²

√49+16

√65

BC= √(3+4)²+(-5+1)²

√49+16

√65

AC= √(3-3)²+(-5-3)²

√0+64

√64= 8

therefore, AB=BC≠AC
