1. Draw a circle of radius 2 cm and centre 0. A point P which is outside a circle and
some distance away from O such that length of the tangent from P to the circle
is root 12cm
Answers
PA is tangent to circle of length = √12 cm of circle with radius = 2cm
Step-by-step explanation:
tangent segment of length √12 cm
Radius = 2 cm
Distance of point p from center = √ ((√12)² + 2²)
= √(12 + 4)
= √16
= 4
Cos θ= 2/4 = 1/2
=> θ = 60°
Step 1 : Draw a circle with radius = 2 cm using compass taking o as center
Step 2 : Draw a Line OP of length = 4 cm
Step 3 : Draw an angle of 60 ° at O on OP and intersect circle at A
Step 4 : Join PA
PA is tangent to circle of length = √12 cm
