Today in class we spent a lot of time going over proofs, which were last night's homework and we didn't have much time to go over the new lesson, but we did learn 3 new definitions from section 1.5.
Bisect: when a point, segment, ray, or line divides a segment into two congruent segments
In this picture, line segment CD bisects angle ACB
Trisect: when two points, segments, rays, or lines divide a segment into three congruent segments.
In this picture, the two dotted lines are trisecting the angle.
Midpoint: a point in the center of a line, the bisection point of a line
In this picture, point C is the midpoint of segment AB
So that's basically what we learned today in class.
