By the end of this topic, I will be able
to…
1. Use perpendicular and angle bisectors
to find missing lengths.
2. Use the properties of bisectors to
identify congruent segments and
angles.
1. Identify concurrent lines and points of
concurrency.
2. Use the properties of bisectors to find
missing measurements and prove
congruence.
1. Be able to distinguish between
medians, altitudes, and bisectors.
2. Be able to distinguish between different
points of concurrency.
3. Use properties of medians and altitudes
to find missing measurements.
1. Use triangle measurements to decide
which side is longest or which angle is
largest.
2. Use triangle inequality construct
triangles.
3. Use the Hinge theorem and its converse
to compare side lengths and angle
measurements.
1. Identify all corresponding parts of
congruent triangles.
2. Prove sides or angles of triangles are
congruent based on the fact that the
triangles were proved congruent.
