Now use the information you already have about finding the equation of a line and apply it to the dashed lines shown in these triangles. Remember, to find the equation of a line you need a point ...
If two lines are drawn at right angles to each other, they are said to be perpendicular. A line drawn to cut another line or angle in half is a bisector. The path of a point that moves according to a ...
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.
