Prove that the mid-point of the hypotenuse of right angled triangle is equidistant from its vertices.

Text Solution

Verified by Experts

Let ABC be a right triangle, right angled at A.
Let D be the midpoint of the hypotenuse BC.
Now it is obvious that `CD = BD = 1/2 BC.`
Since D is the midpoint of BC.
consider, `AD =AB +BD`
