WebThe length of the chord CD parallel to XY and at a distance 8 cm from A, is. (a) 4 cm (b) 5 cm. (c) 6 cm (d) 8 cm. Solution: (d) First, draw a circle of radius 5 cm having centre 0. A tangent XY is drawn at point A. Question 6: In figure, AT is a tangent to the circle with centre 0 such that OT = 4 cm and ∠OTA = 30°. WebNow, look at Fig. 11.2 in which AB is a chord of the circle with centre O. So, shaded region APB is a segment of the circle. You can also note that unshaded region AQB is another segment of the circle formed by the chord AB. For obvious reasons, APB is called the minor segment and AQB is called the major segment.

In given figure, PQ is a tangent at a point C to a circle with centre O. If AB is a diameter and ∠CAB = 30°, find ∠PCA. Solution: Question 3. In figure given, AOB is a diameter of a circle with centre O and AC is a tangent to the circle at A. If ∠BOC = 130°, then find ∠ACO. Solution: WebGIVEN: Chord (which is a diameter) and tangent [See Figure 6(a).] PROVE: PROOF: By Theorem 6.2,. Then is a right angle and. Because the intercepted arc is a semicircle,. Thus, it follows that. EXAMPLE 3. GIVEN: In Figure 6, with diameter , tangent , and FIND: a) c) b) d) SOLUTION a) is an inscribed angle; b) With and a semicircle,. homeless team stockton council
