Six Basic Geometric Constructions

Showing how to 1) copy a line segment, 2) perpendicularly bisect a line segment, 3) draw a perpendicular to a line through a point on the line, 4) draw a perpendicular to a line through a point not on the line, 5) bisect an angle, 6) copy an angle.

June, 2023; the compass is available from Dick Blick art supplies, sold singly:

I substitute an InkJoy pen (commonly found in any office supply, or Walmart) for the pencil. I also use a standard 0.5 mm mechanical pencil because the lead stays uniform in size.
