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. WebNov 3, 2024 · $$\angle PQR =\cos^{-1} \frac{\vec{QP} \cdot \vec{QR}}{(QP)(QR)}$$ To find all interior angles of a triangle, simply using cosine law is good enough. $\dfrac{1}{2} \vec{PQ} \times \vec{QR}$ can be regarded as a vector area of $\Delta PQR$ . sharingham brno
