From a point Q, the length of the tangent to to a circle is 24 cm and the distance of Q from the centre is 25 cm. The radius of the circle is
Given: - Length of tangent = 24 cm, - Distance from Q to center = 25 cm. Using Pythagoras theorem: 25² = 24² + r². Simplify: 625 = 576 + r². Solve for r: r² = 49 ⇒ r = 7 cm.

If the angle between the ratio of a circle is 100°, then the angle between the tangents at the end of these radii is
We are given: - The angle between the two radii of a circle is 100°. Key property of tangents The tangents drawn at the ends of the two radii are perpendicular to their respective radii. Therefore, the angle between the tangents is the **supplement** of the angle between the radii. Calculate the angRead more
We are given:
– The angle between the two radii of a circle is 100°.
Key property of tangents
The tangents drawn at the ends of the two radii are perpendicular to their respective radii. Therefore, the angle between the tangents is the **supplement** of the angle between the radii.
Calculate the angle between the tangents
The sum of the angle between the radii and the angle between the tangents is 180° (since they form a quadrilateral with two right angles). Thus:
Angle between tangents = 180° – Angle between radii.
Substitute the given angle between the radii:
Angle between tangents = 180° – 100° = 80°.

How many parallel tangents can a circle have?
A circle can have two parallel tangents. These tangents will always be parallel to each other and lie on opposite sides of the circle, touching it at two distinct points. Explanation: - A tangent is a line that touches a circle at exactly one point. - For any given direction, there can be two tangenRead more
