WebThe outer circle would form a line having length 2πr forming the base. The height would be ‘r’ Therefore the area of the right-angled triangle formed would be equal to the area of a circle. Area of a circle = Area of triangle = (1/2) × b × h = (1/2) × 2π r × r. Therefore, Area of a circle = πr 2. Properties of Circles WebThe angle between a chord and the tangent at one of its endpoints is equal to one half the angle subtended at the centre of the circle, on the opposite side of the chord (tangent chord angle). If the angle subtended by the chord at the centre is 90 ° , then ℓ = r √2 , where ℓ is the length of the chord, and r is the radius of the circle. WebModified 8 years, 9 months ago.
