Steps of Construction:
1. Take a point O and draw a circle of radius 3cm.
2. Take a point A on the circumference of circle having Centre O.
3. Join the point A to O and produce it to meet the circle at point C.
4. Draw angle m∠AOB=90
5. Draw (BE) ⃡ perpendicular to OB.
6. Draw (CD) ⃡ perpendicular to OC
7. BE and (CD) ⃡ intersect at point P .
8. BE and CD are the required tangents meeting each other at the given angle 90.

The word Geometry is derived from two Greek words
Geo(earth) and Metron (measurement).
Geometry means measurement of earth or land.
Geometry is an important branch of Mathematics which deals
with shape, size and position of Geometric figures.
Euclid’s Elements has been referred to as the most successful
and influential Textbook ever written on Geometry.
A circle of any radius can be constructed by rotating
a compass about a fixed point O.
Circle is a locus of points whose distances from
a fixed point is same
#Tangent
Radius is the distance from Centre to boundary of the circle.
Diameter is a chord passing through the Centre of circle.
