Question

(1,0), (0,1), (1, 1) are the co-ordinates of vertices of a triangle. The triangle is --------- triangle.
(A) Isosceles (B) Obtuse angled (C) Acute angled (D) Equilateral​

Answer 1

Answer:

Let A=(1,0),B=(0,1) and C=(1,1) be the three vertices of the triangle.

By using distance formula we can write.

AB=12+12

​=2

​

BC=12+02

​=1

AC=02+12

​=1

∴BC=AC

∴ The triangle ABC is isosceles triangle.
