1.1.7 Manim(R): Keystone arch Theorem
| keystone arch | pythagorean theorem |
| shape of stones | sidelengths of rect. triangle |
| a hypothetical rule that would give us the shape of the 3rd stone | pythagorean theorem |
| given 2 stones and the river geometry, there is only one more possible stone shape that turns the construction into a bridge | given two sidelengths of a rectangular triangle, there is only one possible sidelength that turns the lines into a triangle |
| voussoirs/supports | legs |
| keystone | hypothenuse |
| River geometry | Rectangular triangle |
