Good evening Irah! Here are my workings for this question.

The first part is purely simuls.

The second part requires you to know that the perpendicular bisector of AB is the line which is perpendicular to AB and passes through the midpoint of AB (to bisect line AB is to cut line AB into two equal parts, which must be done halfway through AB).
