Answer 1

the triangle of sides 3cm,4cm,5cm

and angles of 50,60,70 degrees

draw a rough diagram as above

step1-draw a line segment BC of 5cm. make angle 50degree at C and 60 degree at B.

step-2-draw long line at B andC .

step3- mark A as where both lines intersect drawn from point B&C

step4- measure the angle of A and side AB&AC

step5- triangleABC will be ready
