3.4: Beyond CPCTC

Today in class, we learned about 4 new terms about triangles and their proofs.

These terms are Perpendicular Bisector, Angle Bisector, Altitude, and Median


Perpendicular Bisector- a straight line that is perpendicular to a segment at its midpoint

Angle Bisector- a straight line that divides an angle into 2 equal parts

Altitude- a straight line through a vertex of the triangle and perpendicular to the oppposite side

Median- a straight line from a vertex of a triangle to the midpoint of the oppsite side

Ok thats pretty much everything we learned about in class today. In section 3.4, we will be doing the same thing as 3.3 but going a bit further by using the statement that two triangles are congruent. A few of these terms will also show up in the homework.

Thanks,

Robbie
