Draw a circle of radius 3 cm and take a point P outside it without using centre. Draw 2 tangents to circle. PLEASE GIVE IT TODAY ITSELF.....BECOZ TOMMOROW THIS QUESTION IS THERE FOR EXAM !!!!!!!!!!!
steps of construction:
1. draw a circle with O as center and radius 3 cm.
2. draw a secant PAB from the outer point P. extend AP to point C such that PC = PA.
3. with BC as a diameter , draw a semicircle.
4. at point P , draw a perpendicular PD ⊥ PB cutting the semicircle of step 3 at D.
5. with P as a center and PD as a radius , draw an arc to intersect the given circle at Q and R.
join PQ and PR.
then PQ and PR are the required tangent lines.
