Step-by-step explanation:
Question:
Prove that the points (3,0),(6,4) and (-1,3) the vertices of a right angled isosceles triangle.
Solution:
Given-
A(3, 0), B(6, 4) and C(-1, 3)
=> AB² = (3-6)²+ (0-4)²
=> AB² = 9+ 16
=> AB² = 25
=> BC² = (6 + 1)² + (4 - 3)²
=> BC² = 49 + 1
=> BC² = 50
Now,
= > CA² = (-1 - 3)² + (3-0)²
=> CA² = 16 + 9
=> CA² = 25
Hence,
AB² = CA² => AB = CA
It means triangle is isosceles
Also,
=> 25 + 25 = 50
=> AB² + CA² = BC²
Since Pythagoras theorem is verified, therefore triangle is a right angled triangle.
