Question

Draw $\angle ABC$ of measure ${115}^{\circ }$ and bisect it.

Answer 1

1. Draw a ray $BC$.

2. With the help of a protractor, draw an $\angle ABC$ of ${115}^{\circ }$.

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 $\angle ABC$.
