If the ratio of the angles of a quadrilateral is 2 : 7 : 2 : 7, then it is a

• trapezium

• parallelogram

• square

• rhombus

B.

parallelogram

Clearly, from the ratios, it can be drawn that opposite angles are equal. And the opposite angles of the parallelogram are always equal. ∴  First angle  = 2x = 2 x 20 = 40°
Second angle  = 7x = 7 x 20 = 140°
Third angle  = 2x = 2 x 20 = 40°
Fourth angle  = 7x = 7 x 20 = 140°
