WebThe theorem can also be thought of as a special case of the intersecting chords theorem for a circle, since the converse of Thales' theorem ensures that the hypotenuse of the right angled triangle is the diameter of its circumcircle.. The converse statement is true as well. Any triangle, in which the altitude equals the geometric mean of the two line segments … WebCorrect option is A) In a circle OA=OB= Radius. So, ∠OAB=OBA=40 °. Therefore, ∠AOB=180 °−40 °−40 °=100 °. We know in a circle the angle subtended by an arc at the …

WebSo, ∠AOB = 180º – (40º + 40º) = 100º. As we know that angle subtended by an arc of a circle at the center is double the angle subtended by it at any point on the remaining part of the circle. So, ∠ACB = 1 2 ∠AOB = 1 2 × 100 ∘ = 50º. Concept: Concept of Circle - Centre, Radius, Diameter, Arc, Sector, Chord, Segment, Semicircle ... WebAs the angle subtended by an arc at the centre is twice the angle subtended by it at the remaining part of the circle. ∠AOB = 2 ∠ACB. Substituting the values. 100º = 2 ∠ACB. Dividing both sides by 2. ∠ACB = 50º. Therefore, ∠ACB is equal to 50º. Try This: If ∠OAB = 50º, then ∠ACB is equal to : ☛ Also Check: NCERT Solutions ...
