Today in class with finished our "tool belt", learning all the basic construction skills that we can then synthesize to construct all kinds of triangles, angles, and segments.
The tool belt:
The tool belt:
 Copy a segment (double, add, subtract)
 copy an angle (double, add)
 construct a daisy (regular hexagon)
 construct an equilateral triangle (or a 60 degree angle)
 perpendicular bisector of a segment (locates a midpoint) (also for medians, midsegments in triangles)
 angle bisector of an angle
 perpendicular from a point to a line (also altitude)
 Perpendicular from a point on a line (useful for right triangles and squares, etc.
We added Conjectures 5 and 6 to geometric truth (p 1567) and added p 158:10 to homework #13, also taking a grade on HW #13 for 4 pts. We then figured out how to bisect an angle, to construct a perpendicular from a segment to a line, what is an altitude in a triangle (look up in textbook) and how to construct it, and well as constructing a 90 degree angle on a line. Practice and answers to HW #13 are attached below. MORE HELPFUL: follow the link to the mathopenref constructions menu. Here are some relevant ones to view:  Under lines: copy a segment, add or subtract segments, perpendicular bisector of a segment, perpendicular from an external point to a line, perpendicular from a point on a line.
 Under angles: copy an angle, add or subtract angles, angle bisector
 Triangles: median, midsegment, perpendicular bisector, angle bisector HW #14: p 1623:2,46, p 166:5
