Question

Which construction is represented by these construction marks?

Question 1 options:


A perpendicular line segment AC


The angle bisector of

Copying

The perpendicular bisector of segment BC

Answer 1

The angle bisector of < BAC.

Explanation:

It is the angle bisector of < ABC.

First the arc is drawn Then the compass point is placed at the points where the arc cuts the lines BA and BC and the green arcs are drawn . The line from B to the point of intersection of the 2 green arcs is the bisector of the angle.

Answer 2

The angle bisector of angle ABC

Explanation:

The construction that is represented here is :

The angle bisector of angle ABC.

-------------------------------------------------------------------------------------

The steps to bisect ABC are as follows:

1. Keep the compass tip on the vertex of the angle B.

2. Now, stretch the compass to a length that will stay on the angle.

3. Draw an arc crossing both sides or rays of the given angle. This will give you two intersection points with the rays of the angle.

4. Now keep the compass tip on one of these new intersection points and draw an arc in the interior of the rays.

5. Keeping the compass width same, draw the same kind of arc from the second new intersection point.

6. Now join the vertex of the angle B to this intersection of the two small arcs.

In this way we get the angle bisected.
