• A. $JoinC,B$
• B. $Mark30degreesatA$
• C. $Draw7cmarcfromA$
• D. $MarkintersectionasC$
• E. $DrawlineABof4cm$

Answer 1

Steps of construction for above triangle

Step 1:
Draw a line segment AB of length 4 cm

Step 2:
Mark 30 degrees at point A and extend a line passing through this mark

Step 3:
Draw an arc of radius 7 cm from point A.

Step 4:
Mark the intersection point as C

Step 5:
Join C,B to get the required triangle ABC as shown below
