GEOM 2 | Lesson 4: Properties and Characteristics of Triangles


Learning Intentions (Objectives)

a) Students will develop understanding of medians, angle bisectors, altitudes, and perpendicular bisectors in triangles.

b) Students will use their understanding of the aforementioned lines to solve problems.

Rationale (Diagnostic Results)

You often do not remember the meaning of the terms “median, angle bisector, altitude, and perpendicular bisector.” You may frequently make assumptions about the aforementioned lines e.g. “an angle bisector always cuts the side opposite the angle into two congruent segments” or “lines that look parallel are parallel.”
