WebThe Relationship Between Circles and Right Triangles Consider a circle of radius r with a central angle α, such as shown below. Let's draw a line segment from point P down to (and perpendicular with) the horizontal radius. This construction forms a right triangle with a hypotenuse of length r (the radius of the circle).
