Answer:
Option C, The triangle is an isosceles triangle.
Step-by-step explanation:
On a coordinate plane, triangle A B C is shown. Point A is at (negative 1, 3), point B is at (negative 5, negative 1), and point C is at (3, negative 1).
[tex]\left(-1,3\right), \left(-5,-1\right),\left(3,-1\right)[/tex]
Use distance formula to find [tex]AB^2 , BC^2, CA^2\\AB^2 = (-1+5)^2+(3+1)^2 =32\\AC^2= ((-1-3)^2+(3+1)^2 = 32\\BC^2 = (-5-3)^2+(-1+1)^2 = 64[/tex]
We find only two sides are equal and third side is not equal
Hence this is an isosceles triangle
