Question

1. Construct triange ABC, given that AB =3 cm, BC =5.5 cm and ABC = 60°.​

Answer 1

Answer:

Draw a line segment AB =3cm. 2) With B as center, construct an angle of 60° such that angle ZBA = 60°. 3) With B as center, draw an arc of radius 5.5cm to cut off Z at C such that BC =5.5cm. 4) Join the points A and C.

1. Draw a line segment BC=5.5 cm

2. Through B draw BX such that ∠CBX=60°

3. Draw BY⊥BX.

4. Draw ⊥ are bisector of BC so that it cuts BC at M and BY at O.

5. Draw a circle with centre O and radius OB.

6. The major are BKC of the circle contains the vertical angle 60°

7. With M as centre, draw an arc of radius 4.5 cm meeting the circle at A and A'

8. △ABC or △A'

BC is the require triangle.
