Question
A triangle with vertices (4, 0), (-1, -1), (3, 5) is
Options
A.isosceles and right angled
B.isosceles but not right angled
C.right angled but not isosceles
D.neither right angled nor isoceles
Solution
; So, in isosceles triangle AB = CA For right angled triangle BC2 = AB2 + AC2
So, here BC =
or BC2 = 52 or 
So, given triangle is right angled and also isosceles
