Question

draw a triangle ABC such that BC = 4.5 CM angle b is equal to 40 degree AB - AC = 2 cm​

Answer 1

Answer:

1. Construct a line segment BC of 4.5cm

2. Construct a 45

o

angle at B

3. Take the length of PB as 5.6cm.

4. Join PC

5. Construct a bisector at PC. The line will meet BP at point A. Join AC

We get the required triangle.

Answer 2

Answer:

We are given BC = 4.5 cm,

∠B = 450 and AB - AC = 2.5 cm

Steps of Construction :

(i) Draw a ray BX and cut off a line segment BC = 4.5 cm from it.

(ii) Construct ∠XBY = 450

(iii) Cut off a line segment BC = 2.5 m from BY.

(iv) Join AC.

(v) Draw perpendicular bisector of CD cutting BY at a point A.

(vi) Join AC. So, ΔABC is the required triangle.
