2D Coordinate Rotation
A 2D coordinate can be easily rotated by around another point to give the new rotated point with the equation:         The angle is positive for a counter-clockwise rotation. You may notice that the coordinate is translated as if  was the origin, the rotation transformation is applied, and then it is translated … Continue reading 2D Coordinate Rotation
Circle Geometry
Inscribed angle: An angle made from points sitting on the circles circumference. An inscribed angle is half the central angle. When keeping the end points fixed, an inscribed angle is always the same, no matter where the vertex is. The angle inscribed in a semicircle is always a right-angle. A cyclic quadrilateral has four verticies … Continue reading Circle Geometry
