Construction of Tangents
This video explains the construction of tangents to a given circle from a point on the circle and from a point outside the circle.
- draw a circle of radius 3.4 cm. Draw a chord MN of length 5.7 cm in it construct tangents at M and N to the circle.
- Construct a tangent to circle of radius 4 cm through a point P on its circumference.
- Construct tangents to a circle with centre O from an external point P.
- Draw a circle of radius 4 cm. Take a point P outside the circle. Without using the centre of the circle, draw two tangents to the circle from point P.
- Draw a pair of tangents to a circle of radius 5 cm which are inclined to each other at an angle of 60^{o.}
- Draw a circle of radius 1.5 cm. Take a point P outside it. Without using the centre, draw two tangents to the circle from the point P.
- Draw a pair of tangents to a circle of any convenient radius, which are inclined to the line joining the centre of the circle and the point at which they intersect at an angle of 45^{o}.
- Construct a tangent to a circle of radius 4 cm from a point on the concentric circle of radius 6 cm and measure its length. Also verify the measurement by actual calculation.
- Construct a tangent to a circle of radius 4 cm from a point which is at a distance of 6 cm from its centre.
- Draw a circle of radius 3 cm. Take two points P and Q on one of its extended diameter each at a distance of 7 cm from its centre. Draw tangents to the circle from these two points P and Q.
