Question

Q. Construct a triangle ABC in which BC = 5.5 , angle B = 60
sum of two sides = 8.6cm
​

Answer 1

Explanation:

Step-by-step explanation:

Draw a line BC of 5.5 cm

cut an arc of 180 degree from point B

cut an arc of 60 degree in it

cut an arc of 180 degree from point C

draw an angle of 80 degree on point C

match the angles constructed.

Answer 2

Given : In Δ ABC , BC = 5am , AC + AB = 7.5cm and ∠ B = 60°

To construct : Δ ABC

Steps of construction :

1. Draw a ray BX and cut off a line segment BC = 5cm from it.

2. At B , construct ∠ XBY = 60°

3. With B as center and radius = 7.5cm , draw an arc at meet BY at D.

4. Join CD.

5. Draw the perpendicular bisector of CD, by marking arc of length more than half of CD from both points C and D on both sides of it.

this line will be intersecting BD at A .

6. Join AC .

Then , ABC is the required triangle .
