• Square: A square is a rectangle in which a pair of
adjacent sides are equal.

• Rhombus: A rhombus is a parallelogram having a pair of equal adjacent
sides.

• Trapezium: A quadrilateral having a pair of parallel sides is called a trapezium.

(i) Isosceles trapezium (ii) Right trapezium

• Kite: A quadrilateral having two pairs of equal adjacent sides and
unequal opposite sides is called a kite.

EXERCISE 17.2

1. Write True or False.

(c) A square can be thought of as a special rhombus.
(d) Square is also a parallelogram.

3. Draw a rough sketch of a regular hexagon. Join any four vertices of the hexagon to make a
rectangle. Can you also draw a trapezium by joining vertices of the hexagon?
4. What is the sum of opposite angles of a square?

5. What is the difference between any two adjacent angles of a rectangle?
