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).
Use distance formula to find
We find only two sides are equal and third side is not equal
Hence this is an isosceles triangle
