WebPerimeter is the distance around a two-dimensional shape. Example: the perimeter of this rectangle is 7+3+7+3 = 20. Example: the perimeter of this regular pentagon is: 3+3+3+3+3 = 5×3 = 15 . The perimeter of a circle is called the circumference: WebTheorem: The angle subtended by an arc of a circle at its center is twice the angle it subtends anywhere on the circle’s circumference. The proof of this theorem is quite simple, and uses the exterior angle theorem – an exterior angle of a triangle is equal to the sum of the opposite interior angles. If the two opposite interior angles ...
