Constructing Perpendicular Bisectors and Medians

The video tutorial explains how to construct the median of a triangle using a compass. It begins with an introduction to the concept of a median, followed by a sketch of the triangle. The tutorial then details the steps to construct the perpendicular bisector to find the midpoint of the opposite side. Finally, it shows how to draw the median by connecting the vertex to the midpoint. The video concludes with tips on ensuring accuracy in construction.

What is the first step in constructing the median of a triangle?

• Labeling the triangle vertices

• Connecting the vertex to the midpoint

• Finding the midpoint of the opposite side

• Drawing the triangle

What does the median of a triangle connect?
