Question

draw a pair of tangents to a circle of radius 4.5 CM which are inclined to each other at an angle 80degree​

Answer 1

$\huge\boxed{\tt\underline{Answer}}$

• Draw circle of radius 4.5 cm with centre O.
• Take any points A on the circle. Join OA. Mark another point B on the circle such that

∠AOB = 135°, supplementary to the

angle between the tangents.

Since the angle between the tangents to be constructed is 45°.

∠AOB = 180° 45° = 135°.

• Construct angles of 90° at A and B and extend the lines so as to intersect at point P.
• Thus, AP and BP are the required tangents to the circle.
