Question

construct a triangle abc whose perimeter =10 cm and two acute angle are 30 and 60

Answer 1

step 1 : draw XY=10cm (perimeter given)
step 2: on X and Y construct <30 and <60
step 3: bisect the angles and mark their point of intersection as a
step 4: bisect AX and AY and extend the line bisecting them on XY and mark the point on which they meet XY as b and c 
step 5: join AB and AC 
 
ABC is the required triangle
