Q6 of 57 Page 63

Is the following statement true? Why? ‘‘Two quadrilaterals are similar, if their corresponding angles are equal’’.

(False)

Just one corresponding angle on either quadrilateral isn't enough to say that they would be similar. To be similar, with the corresponding angles of each they should also have proportional corresponding sides.
