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.
