Solution:
Given:
To draw the perpendicular bisector of each side, place the compass at the two ends of the line.
Using the line WX, expand the compass to beyond half of the line and place the compass at the first point (point W), to draw an arc above and below.
Then place the compass at the other point of the line (point X), and draw an arc to intersect the initially drawn arcs.
Join the two points of intersection to get the perpendicular bisector of the line.
Repeat the same for the other two sides to get the perpendicular bisectors.
