Question

Construct a triangle ABC in which BC = 5.5 cm,B = 75° and AC - AB = 2 cm. 6m Construct a triangle ABC in which BC = 4.5 cm, ZB = 30° and AB - AC = 2.5 cm.​

Answer 1

Step-by-step explanation:

Steps of Construction:

(i) Draw a line segment which is sufficiently long using ruler.

(ii) Locate points A and B on it such that AB=4.5cm.

(iii) At A, construct a line segment AE, sufficiently large, such that ∠BAC at 60

∘

, use protractor to measure 60

∘

(iv) With A as centre and radius 5.5cm, draw the line cutting AE at C, join BC.

Then ABC is the required triangle
