Activity 3 - Triangles, Medians and Right Triangles
Fact: If the median (line joining vertex and midpoint of opposing side) is half the length of that side, then the triangle is a right triangle.
User interacts with construction and notes that the triangle "appears" to be a right triangle. Then, using only the fact that the lower angles of an isosceles triangle are equal, the user "proves" that the angle is in fact 90°. Finally, user constructs the same interactivity.
Materials include handout for student and teacher page (in pdf and doc format), ggb files for offline use and/or interactive page for online use.
