Question

.
Draw ABC = 80° with the help of a protactor. Draw its angle bisector.​

Answer 1

Step-by-step explanation:

Construct a ray OB

Using the protractor construct ∠AOB of 80o

Considering O as centre and convenient radius construct an arc cutting the sides OA and OB at the points Q and P

Considering Q as centre and radius more than half of the angle PQ, construct an arc

Considering P as the centre and radius more than half of the angle PQ, construct another arc which intersects the previous arc at the point R

Join the points OR and produce it in order to from a ray OX

Therefore, OX is the bisects of the ∠AOB

So the measure of each parts of the bisected angle is ∠AOX=∠BOX=40

o

Answer 2

$\gamma \a n swer$

1.angle ABC angle bisector =BD

2.angle ABC =80°

3.angle ABD =40°

4.angle DBC=40°

✔HOW TO DRAW ✔

step by step explanation

draw line BC and using protractor mark

80° and then draw an arc from point B by using compass .You can take any radius

now you could extend the compass a little bit.The arc which we draw from that arc draw another two arcs then we could find the other angles and the angle bisector okay...
