Question

prove that the opposite sides and angles of a parallelogram are equal

Answer 1

Consider a parallelogram ABCD...Now stretch all the four sides. At one point you will find that AB is intersecting AD .The same case happens with the other sides.Now it is also noticeable that we can make corresponding angles..Now find two pairs of corresponding angle, one pair on the line and one below the same pair of lines.Equate them both and cancel... You will find the angles of rhe parallelogram are equal!!!!
