(a) If a point P lies inside a circle, no tangent can be drawn to the circle passing through P.
(b) If a point P lies on a circle, then one and only one tangent can be drawn to the circle at P.
(c) If a point P lies outside a circle, then only two tangents can be drawn to the circle from P.
(d) A circle can have more than two parallel tangents parallel to a given line.
P lies in the exterior of 🔘 (O, 5 )such that op=13. Two tangents are drawn .to the circle which touch the circle in A and N.find AB
You are given a circle with radius 'r' and centre 'O'. You are asked to draw a pair of tangents which are inclined at an angle of 60° with each other, from a point E.
Refer to the figure and select the option which would lead you to the required construction. The distance d is the distance OE.
Using trigonometry, arrive at d = r and mark E.
Construct the △MNO as it is equilateral triangle.
Mark M and N on the circle such that ∠MOE = 60∘ and ∠NOE = 60∘.
Mark M and N on the circle such that ∠MOE = 120∘ and ∠NOE = 120∘.
