Geometric Challenge

Problem 1620: Perpendicular Chords and Opposite Areas, a Hidden Linear Invariant

Share your proof or solution in the comments below.
Target Audience: K-12, Honors Geometry, and College Mathematics Education.

Uncover the mathematical elegance hidden within a circle. In Problem 1620, we explore how two perpendicular chords partition a circle into four curvilinear regions to reveal a remarkable hidden area difference invariant.
Explore the full theorem and illustrated diagrams by clicking the image below.

Adding technology to geometry class improves opportunities to learn

A new study co-written by a University of Illinois expert in math education suggests that incorporating technology in high school-level geometry classes not only makes the teaching of concepts such as congruency easier, it also empowers students to discover other geometric relationships they wouldn’t ordinarily uncover when more traditional methods of instruction were used.

Australia: Math in crisis as teachers go private

Education

Advanced mathematics is disappearing from public school classrooms, leaving students able to learn only basic math, because the few qualified teachers are being snapped up by the private sector. Source: The Australian by Andrew Trounson.
