As remote learning and hybrid classrooms become permanent fixtures in the educational landscape, tools like geometry-lessons.github.io will likely become the standard, rather than the exception.
It solves the "homework problem." In a traditional model, a student struggles through problems at home and gets feedback days later. With dynamic lessons, the feedback is instant. If a student drags a point and the theorem holds true, they have proven it to themselves immediately.
Before the leap to Algebra II, geometry students master the Pythagorean Theorem, 45-45-90 and 30-60-90 triangles. A quality resource like this would also introduce SOH-CAH-TOA as a geometric concept, not just a calculator trick. Expect clear visuals showing the opposite and adjacent sides relative to a given angle. geometry-lessons.github.io
You might wonder: Why a .github.io site?
Because it’s:
Central angles, inscribed angles, tangents, and power of a point. Circles have some of the most elegant theorems in all of math.
Prisms, pyramids, cylinders, cones, and spheres. Surface area and volume explained without the guesswork. As remote learning and hybrid classrooms become permanent
The transition from 2D to 3D. Surfaces of prisms, pyramids, cylinders, cones, and spheres. The best geometry sites provide 3D wireframe models that students can rotate with their mouse. Given that GitHub pages supports WebGL libraries, it is probable that geometry-lessons.github.io offers interactive 3D nets you can unfold.
