Question

construct a triangle abc in which angle b= 30 , angle c =60 and AB +BC+CA= 12 cm ​

Answer 1

Step-by-step explanation:

steps

(1) draw a line segment of length 12 cm and name the ends say as X and Y.

(2) construct 30° at X and 60° at Y

(3) draw angle bisectors at X and Y and extend the angle bisectors to meet at A.

(4) draw perpendicular bisectors of angle bisectors XA and YA to meet line drawn in step 1 ( X Y) say at B and C.

(5) now join ABC and the ∆ is ready
