Prove that, ABOC is a square. Given: O is the centre of circle. seg AB and seg AC are the tangents, radius = r, / (AB) = r. To prove: ABOC is a square. WebSolution: Question 2. 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:

WebFigure 1: Segment of a Circle Derivation. In fig. 1, if ∠AOB = θ (in degrees), then the area of the sector AOBC (A sector AOBC) is given by the formula; (A sector AOBC) = θ/360° × πr 2. Let the area of ΔAOB be A ΔAOB. So, … Webtangent to a circle through a point inside it [see Fig. 10.6 (i)]. Next take a point P on the circle and draw tangents through this point. You have already observed that there is only one tangent to the circle at such a point [see Fig. 10.6 (ii)]. Finally, take a point P outside the circle and try to draw tangents to the circle from this point. WebThe circumference of a circle is the perimeter of the circle (especially when referring to its length). A circle is a special ellipse in which the two foci are coincident. Circles are conic sections attained when a right circular cone is intersected with a plane perpendicular to the axis of the cone. Further terminology. intimate partner violence definition who
