Here are several geometry problems and investigations. The geometry content of these pages target the high school level. It is possible that students of other levels will be successful, too!
1-1: Construct a plane intersecting a prism (box) diagonally.
1-2: Copy segments and add them.
1-3: Plot the midpoints of segments.
2-3: Construct edges of a prism.
3-4: Construct a regular hexagon inscribed within a circle.
4-3: Construct a triangle congruent to a given triangle.
4-4: Construct a right triangle congruent to the given right triangle.
Chords: Use two chords to find a circle’s center.
