Product Description

This activity takes students through each step of sketching and writing the equation of the following within a triangle: Median, Perpendicular Bisector, and Altitudes.

The following concepts are covered: finding the midpoint of a line segment, writing equations of lines (particularly in point-slope and slope-intercept forms), and recognizing that perpendicular lines will have slopes that are opposite reciprocals.

Students are first to plot the given points and connect them creating a triangle. The directions guide them to either finding the midpoint or relevant slopes.

I had students start independently, then allowed for collaboration, and then we synthesized our findings as a class. My students needed lots of practice of these types of questions, so I had them summarize "five key steps" to finding the equation of an altitude when we were done.

This could also be done as guided notes for direct instruction.
