Geometry can be a challenging subject for students, especially when it comes to identifying medians, altitudes, angle bisectors, and perpendicular bisectors. These concepts are essential to ...

Look through the slideshow below to see examples of the special lines in a triangle.

The six intersection points of a triangle’s non-parallel altitudes and perpendicular bisectors are the vertices of two congruent minor periambic triangles which are inversely similar to the original.

This method involves drawing two chords (straight lines connecting any two points on the circumference) within the circle that do not intersect each other. Next, draw a perpendicular bisector for each ...

In the diagram below, AB is the chord of a circle with centre O. OM is perpendicular to AB (meet at a right angle). Look at triangles OAM and OBM. The hypotenuses (OA and OB) are the same, as they are ...
