Guided Proof of Law of Cosines
An enrichment activity for advanced classes or students needing a challenge. A two-column proof of the Law of Cosines, using right triangle trigonometry, is provided for the teacher. On the student handout, the steps are present, but out of order. Students are asked to cut the steps out and the re-arrange them into a logical sequence. A teacher could ask for a written or spoken explanation of why the steps work if desired.

A Collapsible Compass
Sometimes an article or an activity provides the stimulus for further investigations or explorations. Such was my reaction when I first read that a “collapsible compass” was used by Euclid instead of a “modern compass” to deduce his theorems in his book, Elements, which is considered one of the most influential works in the history of mathematics. You may use this activity to challenge yourself to show the equivalence of the “collapsible compass” with the “modern compass,” or challenge your m

Geometric Construction Notes Project
The word construction in geometry has a very specific meaning: the drawing of geometric items such as lines and circles using only compasses and straightedge or ruler. Very importantly, you are not allowed to measure angles with a protractor, or measure lengths with a ruler.
These are the basic geometric constructions you are going to construct:
- Copying a segment, segment addition and difference of two line segments
- Segment bisector
- Copying an angle (congruent angle)
- Angle bisector

The Story of Geometry | Montessori | Strike the Imagination
he Story of Geometry A Montessori Cosmic Story Connecting Math, Nature, and Human Curiosity Long before people used words like angle, radius, or polygon, they noticed patterns. They saw the spiral of a shell. They watched the symmetry of leaves. They looked at the stars and wondered about the shapes of the universe. Geometry began with observation.This Montessori-inspired lesson invites children to explore how geometry emerged from humanity’s curiosity about patterns in the natural world.T
