 Hi and welcome to the session. I am Neha and today I am going to help you with the following question. The question says A, B, C is a right angle triangle and O is the midpoint of the side opposite to the right angle. Explain why O is equidistant from A, B and C. The dotted lines are drawn additionally to help you. And here is the figure. So let's start its solution. In this figure we have drawn A, D parallel to B, C, A, B parallel to D, C. Therefore A, B, C, D is a parallelogram. In question we are given that A, B, C is a right angle to triangle. That means angle A, B, C is a right angle and thus we can say that A, B, C, D is a rectangle. Do you know why I called A, B, C, D a rectangle? Because a parallelogram with a right angle is a rectangle. We know that the diagonals of a rectangle are equal and bisect each other. Therefore we can say that A, C and B, D are equal bisect each other. Thus O is the midpoint of A, C and B, D. So let's write that therefore A, O is equal to O, C is equal to O, B is equal to O, D. But we need to show that A, O is equal to O, C is equal to O, B. Or we can say that O is equidistant from A, B and C. Thus our final solution for this question is that A, D is parallel to B, C. A, B is parallel to D, C. So in parallelogram A, B, C, D, the midpoint of diagonal A, C is O. So with this we finish this session. I hope you must have understood the question. Goodbye and take care.
