The triangle with vertices at (-2,2),(2,-2) and (1,1) is

Options

  1. Ascalene triangle
  2. Bequilateral triangle
  3. Cisosceles triangle
  4. Dright-angled triangle

Correct answer

C. isosceles triangle

Step-by-step solution

Let A(-2,2), B(2,-2) and C(1,1) are the vertices of A B C . array r A B= (2+2)^2+(-2-2)^2 = 4+4 =4 2 B C= (1-2)^2+(1+2)^2 = 1+9 = 10 A C= (1+2)^2+(1-2)^2 = 9+1 = 10 array A B C is an isosceles triangle.
