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.[br]Step 2: Click on the segment you wish to measure. [br]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.[br]Step 2: Click on the segment on which you want to place the midpoint.[br]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.[br]Step 2: Click on a midpoint then the opposite vertex to create a median.[br]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 [i]Median Theorem[/i] is?
