but most theorems and examples.
Answer:
Q.1: How many tangents can be drawn from the external point to a circle?
Answer: Two tangents can be drawn from the external point to a circle.
Q.2: Given: A triangle OAB which is an isosceles triangle and AB is tangent to the circle with centre O. Find the measure of ∠OAB.
Answer: The measure of ∠OAB in the given isosceles triangle OAB will be 45 degrees.
Q.3: What should be the angle between the two tangents which is drawn at the end of two radii and are inclined at an angle of 45 degrees?
Answer: The angle between them shall be 135 degrees.
Q.4: Given a right triangle PQR which is right-angled at Q. QR = 12 cm, PQ = 5 cm. The radius of the circle which is inscribed in triangle PQR will be?
Answer: The radius of the circle will be 2 cm.
Q.5: Define Tangent and Secant.
Answer: A tangent is a line which meets the circle only at one point.
A secant is a line which meets the circle at two points while intersecting it. These two points are always distinct.
Q.6: What is a circle?
Answer: If we collect all the points given on a plane and are at a constant distance, we will get a circle. The constant distance is the radius and the fixed point will be the centre of the circle
