Circle Theorems Problem Solving Youtube Show video lesson. circle theorems part 1 of 2. the angle between a radius and a tangent is 90 degrees. the angle at the centre is twice the angle at the circumference. angles in the same segment are equal. the angle in a semi circle is always 90 degrees. the opposite angles in a cyclic quadrilateral always add up to 180 degrees. Example: find the value of ∠ x in the figure below. solution: ∠ x = 38˚ because they are both subtended by the same arc prq. (1) inscribed angles from equal arcs are equal. (2) arcs that contain equal angles are equal. (1) the measure of the inscribed angle is half the measure of the central angle.
Circle Theorems Notes Corbettmaths The angle at the centre of a circle is twice any angle at the circumference subtended by the same arc. the following diagrams illustrates the inscribed angle theorem. example: the center of the following circle is o. bod is a diameter of the circle. find the value of x. solution: ∠boc 70˚ = 180˚. Example 3: consider the circle given below with center o. find the value of y using the circle theorems. solution: to find the value of y, we will use the circle theorem 'the angle subtended by a chord at the center is twice the angle subtended by it at the circumference. '. so, ∠por = 2∠pqr. Example 5: chord of a circle (cosine ratio) below is a circle with centre c. points a, b, c, and d are on the circumference of the circle. the chord ab is perpendicular to the line cd at the point e. the line ae is 5cm 5cm and angle ade =71o = 71o. calculate the length of the line bc correct to 1 1 decimal place.
