On a piece of graph paper, plot the following points: A (0, 0), B (5, 0), and C (2, 4). These coordinates will be the vertices of a triangle. Using the Midpoint Formula, what are the midpoints of the triangle's side, segments AB, BC, and CA?
We can find all the midpoints before we plot anything. We have sides:
The co-ordinates of the midpoint of a line segment is given by:
We now plot all the points and construct the triangle:
