Question

use the proper geometrical instrument to construct the following angles. use thecompass and the ruler to bisect the angles 115⁰ and 90⁰​

Answer 1

Step-by-step explanation:

1. Draw a ray BC.

2. With the help of a protractor, draw an ∠ABC of 115∘.

3. With one end of the compass at B, mark two equidistant arcs on rays BA and BC.

4. From the two points on the rays, draw two intersecting arcs. Join B to the intersection point of those arcs. 

Ray BM is the angle bisector of ∠ABC.

Answer 2

Steps of Constructions:

(1) Draw an angle ∠ABC of measure 50°.

(2) Now place the point of a compass on point B and with any convenient distance draw an arc to cut rays BA and BC. Name the points of intersection as P and Q respectively.

(3) Now, place the point of the compass at P and taking a convenient distance, draw an arc inside the angle. Using the same distance, draw another arc inside the angle from the point Q, to cut the previous arc.

(4) Name the point of intersection as point O. Now draw ray BO. Ray BO is the bisector of ∠ABC.
