Question

Using protactor, draw a right angle. Bisect it to
get
an
measure of
angle 45°​

Answer 1

Step-by-step explanation:

At first,

draw a straight line and keep the protector on the first left point .The middle line of the protector is toughes with the horizontal line that is made first.

Then mark a point the 90 degree angle with the help of the protector the draw a line and join the point and the horizontal line.

Finally, 90 degree angle is ready.

Answer 2

Answer:

Steps of construction :

(i) Using a protractor, draw a right angle, ∠ABC=90∘.

(ii) With centre B and a suitable radius, draw an arc which meets BC at E and BA at F.

(iii) With centre E and F, draw arcs intersecting each other at G.

(iv) Join BG and produce it to D.

Then BD is the bisector of ∠ABC

∴  ∠DBC=12×90∘=45∘.
