Draw a circle and two lines parallel to a given line such that one is tangent and the other, a secant to the circle.

Fill in the blanks Draw a circle and two lines parallel to a given line drawn outside the circle such that one is a tangent and the other, a secant to the circle.

Fill in the blanks (i) A tangent to a circle touches it in …... Point (s). (ii) A line intersecting a circle in two points is called a ….. (iii) Number of tangents can be drawn to a circle parallel to the given tangent is …. (iv) The common point of a Tangent to a circle and the circle is called ..... (v) We can draw ..... tangents to a given circle. (vi) A circle can have ..... parallel tangents at the most.

Two different non-parallel lines meet the circle abs(z)=r . One of them at points a and b and the other which is tangent to the circle at c. Show that the point of intersection of two lines is (2c^(-1)-a^(-1)-b^(-1))/(c^(-2)-a^(-1)b^(-1)) .

Draw a circle of radius 6 cm. From a pint 10 cm away from its centre, construct the pair of tangents to the circle and measure their lengths.

Prove that the lines which are parallel to the same line are parallel to each other.

In the adjacent figure, which lines are tangents to the circle ?

The lengths of the two tangents from an external point to a circle are equal.

Draw a circle of radius 4 cm and take a point P on it. Without using the centre of the circle, draw a tangent to the circle at P.

Draw a circle with any radius. Draw four tangents at different points. How many more tangets can you draw to this circle ?
