# MPM2D1-02 Geometry review and Midpoint 2016-09-28

We quickly reviewed some terms from yesterday, like scalene triangle, median, altitude, and segment bisector.

Then we learned how to calculate the coordinates of a midpoint if you know the coordinates of the endpoints.

If the endpoints are $(x_1, y_1)$ and $(x_2, y_2)$ then the midpoint is $\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)$.
