Answer 1

Answer:

To Construct triangle ABC where BC= 6.5 cm, AB=4.5 and angle ACB =60.

Step 1: Draw a base of 6.5 cm

Step 2: From vertex B cut an arc of 4.5 cm.

Step 3: From vertex C draw 60 degree with the help of protactor

Step 4: The extended line and arc gets coincides at point A.

and your triangle is formed.

Answer 2

Answer:
