Distance Formula CBSE NCERT solutions Chapter 7 Exercise 7.1 Question 4
4. Check whether (5, -2), (6, 4) and (7, -2) are the vertices of an isosceles triangle.
Solution:
Let A = (5, -2), B = (6, 4) and C = (7, -2)
Using Distance Formula to find distances AB, BC and CA.
We can see that AB = BC. Therefore, A, B and C are vertices of an isosceles triangle.
