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.
