Question

What is the next step in the construction of an angle bisector of angle ABC?

Answer 1

Option A is right

Explanation:

Given in the picture is an angle B formed by line segments AB and BC

To construct bisector of angle B

First with centre at B a circle is drawn which meets AB and BC at D and E respectively. With same radius equal to DE and centres of D and E two circles are drawn which intersect at the right most point.

The next step is join B to the rightmost vertex of equilateral triangles

This will be the angle bisector of angle ABC

Hence option A is right

Answer 2

A. Use straightedge to connect vertex B to right-most vertex of the equilateral triangle.

Explanation:

The process is to create a bisector of angle ABC... so it means cutting angle at vertex/summit B in half.

Drawing a line from the vertex B to the right-most vertex of the equilateral triangle will deliver you the bisector.

The only answer choice that includes vertex B is the answer A, all other answers are dealing with vertex A and C... which will not help you to draw the bisector or angle ABC.
