How to solve circle theorems
WebCircle theorems can be used to solve more complex problems. When calculating angles using a circle theorem, always state which theorem applies. It may not be possible to … WebThe area of an equilateral triangle with side length s is s²√3/4. Since we know the areas of these triangles, we can solve for their side lengths: s²√3/4=9√3. s²/4=9. s²=36. s=6. So the triangles have sides of length 6. And when follow a diameter of the circumcircle, we trace two sides of equilateral triangles.
