Question

ABCD is a rectangle formed by the point A (-1,-1), B (-1,4), C (5,4),D (5,-1). If p,q,r,s be the midpoints of AB,BC, CD,AD show that pqrs is a rhombus ​

Answer 1

Answer:

• the mid point between AB will be ( -1,5/1);
• " " " " BC will be ( 2,4);
• " " CD will be ( 5,5/1);
• AD will be (2,-1);
• thus these points will make a rhombus whose side is equal but not angle
