Geometry Activities

Notes and worksheets are no substitute for practical life experiences with geometric applications, and the durable episodic memories they produce.

Proportions Relating to the Golden Ratio (Grades 6-7).

The ratio of your forearm to hand is Ф=Phi pronounced "Fi"  like fly.                          Your hand creates a golden section in relation to your arm, as the ratio of your forearm to your hand is also 1.618, the Divine Proportion.                           Forearm/hand = Ф= Forearm + hand/forearm.
