Question

ABCD is a rhombus and P Q R and S are the midpoints of the sides AB BC CD and DA respectively show that the quadrilateral PQRS is a rectangle

Answer 1

here AC perpendicular to BD
p and q are the mid point s of ABand BC
PQ parallel to AC
AC perpendicular BD
PQ perpendicular BD
again PS PARALLEL BD
measure angle P will be right angle
similarly we can prove other angles are right angles

Hope it will be useful
