Question

A triangle with vertices (4, 0), (- 1,-1) and (3, 5) is a/an

a) equilateral triangle
b) right -angled triangle
c) isosceles right-angled triangle
d) none of these​

Answer 1

Answer:

C. isosceles right angle triangle.

Answer 2

Answer:

Isosceles right angled triangle

Step-by-step explanation:

A(4, 0), B(-1, -1), C(3, 5) are the vertices of a triangle. Then

AB² = (-1-4)² + (-1-0)²= 26

BC² = (3+1)² + (5+1)²= 52

CA² = (4-3)²+ (0-5)²= 26

This implies, CA² + AB² = BC²

Thus, the triangle is isosceles and right angle triangle.

The correct option is C.
