Question

- ABCD in which AB = 4.2 cm, BC = 4.5 cm, CD = 4 cm, DA = 4.8 cm, and angle A = 72º construct a quadrilateral
.​

Answer 1

Answer:

Given : ABCD in which AB=4.2cm, BC=4.5cm, CD=4 cm, DA=4.8 cm and angle A =72°

To Find :  construct Triangle

Solution:

Step 1  :  Draw a line segment AB = 4.2 cm

Step 2 :  Draw a ray at an angle of 72° at A on BA using protractor.

Step 3 :  Using compass width = 4.8 cm and taking A  as center cut the ray  drawn in previous step at D

Step 4 :  Using Compass width = 4.5 cm and taking B as center draw an arc

Step 5 : Using Compass width = 4 cm and taking D as center draw an arc intersecting arc drawn in previous step at C

Step 6 :  Join BC  &  CD.

Quadrilateral ABCD is constructed.
