Gaurav Seth 6 years, 10 months ago

Given A(3, 0), B(6, 4) and C(–1, 3)

AB^2 = (3 – 6)^2 + (0 – 4)^2


= 9 + 16 = 25 


BC^2 = (6 + 1)^2 + (4 – 3)^2


= 49 + 1 = 50 


CA^2 = (–1 – 3)^2 + (3 – 0)^2

 

= 16 + 9 = 25 


AB^2 = CA^2 ⇒ AB = CA


Triangle is isosceles

Also, 


25 + 25 = 50

 

⇒ AB^2 + CA^2 = BC^2

 

Since Pythagoras theorem is verified, therefore

Triangle is a right angled triangle
