Question

Draw a triangle ABC in which AB = 5.1 cm, BC = 4.3 cm and angle B=60 . Draw the bisectors of the angles C and A of the triangle, meeting at a point I. Measure angle CIA.

​

Answer 1

Step-by-step explanation:

!(BAD)=!(DAC)=60

0

=60

0

1.Draw a line segment AB=3cm

2. Using protractor from B measure from 0

∘

and mark a point at 120

∘

3.From the point A using compass draw an arc of length 3cm

∴AB=AC=3cm

4.Join BC

5.Draw an arc at ∠A

6.Bisect the arc at ∠A and name the point of intersection of the arc as D

7.Join AD

thereforeAD is the angle bisector.

Hence ∠BAD=∠DAC=60
