Question

Construct ∆ABC in which ∠B=70° ∠C=60°AB+BC+AC =11.2CM​

Answer 1

Step-by-step explanation:

Steps of construction:

(1) Draw seg XY of 11.2 cm length.

(2) Draw a ray making angle of 35

∘

at point X.

(3) Draw another ray making an angle of 30

∘

at point Y.

(4) Name the point of intersection of the two rays as A.

(5) Draw the perpendicular bisector of seg AX and seg AY.

Name the points as B and C respectively where the perpendicular bisectors intersect line XY.

(6) Draw seg AB and segAC.

Therefore, ΔABC is the required triangle.
