Ex 6.1, 3
State whether the following quadrilaterals are similar or not :
Two polygons of same number of sides are similar if;
(a) Their corresponding angles are equal and
(b) Their corresponding sides are in the same ratio.
In case of PQRS and ABCD,
The corresponding angles do not appear equal.
And, ∠ DAB = 90°
But, ∠ SPQ ≠ 90°
Hence, first condition not satisfied. So, they are not similar.
