Triangle Median Theorem
Part 1: Measure the segments
Step 1: Click on the angle icon, then on the distance or length icon in the drop down menu.
Step 2: Click on the segment you wish to measure.
Step 3: Repeat for the remaining two segments.
Part 2: Creating midpoints
Step 1: Click on the point icon, then on the midpoint or center icon in the drop down menu.
Step 2: Click on the segment on which you want to place the midpoint.
Step 3: Repeat for the remaining two segments.
Part 3: Creating medians - segments connecting a midpoint and the opposite vertex
Step 1: Click on the line icon, then on the segment icon in the drop down menu.
Step 2: Click on a midpoint then the opposite vertex to create a median.
Step 3: Repeat to create three medians.
Part 4: Discovering the median theorem
Drag each of the points of the original triangle around, paying close attention to the medians. What do you notice? What do you think the Median Theorem is?
