Question

draw a circle of radius 1.8 cm . take a point p on it. draw a tangent to the circle at the point p.​

Answer 1

Draw a circle of radius 1.8 cm ,take a point p on it. draw a tangent to the circle at the point p.

steps of construction :

1. Draw a circle of radius 1.5 cm . Take a point P outside it
2. Through P draw a secent PAB to meet the circle at point A and B
3. Produce AP to C such that PC = PA . bisect CB at Q
4. Draw PD ⊥ CB , cutting the semi-circle at the point D
5. with P as centre and PD as radius an arc to cut the circle at T and T' .PT and PT' are required
