Area of a Sector Fast!
To find the area of a sector, use this magic shortcut:
Area = (θ / 360) × π × r² where θ is the central angle!
Try with r = 10, θ = 45°!

Circumcenter Trick!
Find the circumcenter by drawing perpendicular bisectors of any two triangle sides. Where they meet is the center!

Regular Polygon Area!
For a polygon with n sides and side length s, use:
Area = (n × s²) / (4 × tan(π/n)). Try with n=5, s=6!
