Project 4
Construct a line segment and an angle congruent to the given line
segment and angle.
Now construct an equilateral triangle, a square, a regular pentagon, a regular hexagon, a regular octagon, a regular dodecagon (12 sided) and a regular 15-gon, using nothing but a straightedge and a compass. (Use colored pencils or pens to show important steps.)
Finally, use the following line segments to form a quadrilateral.
Can you inscribe a circle in this quadrilateral? If so, do so and find the center of the circle and discuss the radius. If not, explain why not.
