MAHARASHTRA Class 10: Distance Formula Videos | Distance Formula

The distance formula is given by

The distance formula is given by

Now, we get

BC² = AB² + AC²

So, the right-angled triangle 

A (0,−1), B (6,7), C (−2,3) and D (8,3)

The distance formula is given by

AD = BC and AC = BD and AB = CD

The opposite sides are equal and so are the diagonals; hence, ADBC is a rectangle.
