Question

Dont Whlch 2A = 120° and AB = AC = 3 cm. Draw the bisec
angle A.
. Construct a triangle ABC in which ZB = 90° and AB = 4 cm and BC = 3 cm.with steps​

Answer 1

Answer:

60 ∘

Explanation:

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  ∘
