Q7 of 26 Page 235

Draw a circle with the help of a bangle, Take a point outside the circle. Construct the pair of tangents from this point to the circle measure them. Write conclusion.

Step1: Draw a circle with bangle, its center is not known



Step2: to find the center draw 2 random chords C and FE



Step 3:Find the perpendicular bisectors of these chords, the points where they intersect is the center of circle



Step 4:


Draw a line from center to a point outside it.


Step 5: draw its perpendicular bisector



Step 6: Cut arcs over the circle with this point as center and point outside it as radius


Step 7: Draw tangent to the circle where the arcs cut the circle

Draw a circle of radius 6 cm. From a point 10 cm away from its centre, construct the pair of tangents to the circle and measure their lengths. Verify by using Pythogoras Theorem.

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.

In a right triangle ABC, a circle with a side AB as diameter is drawn to intersect the hypotenuse AC in P. Prove that the tangent to the circle at P bisects the side BC.

Draw a tangent to a given circle with center O from a point ‘R’ outside the circle. How many tangent can be drawn to the circle from that point?

Hint : The distance of two points to the point of contact is the same.
