## Karnataka Board Class 8 Maths Chapter 15 Quadrilaterals Ex 15.5

Question 1.
Construct rectangle ABCD with the following data.
(a) AB = 4 cm, BC = 6 cm.
Opposite sides of a rectangle are equal as each angle is a right angle.
∴ AB = CD = 4 cm.
Steps:

1. Draw a line segment AB = 6 cm.
2. Construct a perpendicular at B.
3. With a 7 cm radius at A as center draw an arc on the perpendicular. Let the point be C.
4. With BC as radius draw an arc from A.
5. With AB as radius cut the arc from A.

(b) AB = 6 cm AC = 7.2 cm
Steps:

1. Draw a line segment AB = 6 cm.
2. Draw perpendicular at B.
