Goals

What is a perpendicular bisector?

Drawing perpendicular bisectors

1. Draw line segment AB with a length of 4 cm.
2. Draw the perpendicular bisector of AB with a length of 4 cm.

Drawing perpendicular bisectors

1. Draw a triangle DEF with any shape and dimensions.
2. Draw the perpendicular bisectors of sides DE, EF, and DF.
3. Label the intersection point of the perpendicular bisectors as M.
4. Measure the distances between M and the vertices.

Example:

Sketch your triangle

pag. -
