Question

Two circles of radii 3 cm each have their centres 6 cm apart. Draw a transverse common tangent.

Answer 1

Draw a line segment $AB$ of length $6cm$.

Draw a circle $C1$ of radius $R_1=3cm$ at $A$ and $R_2=3cm$ at $B$.

Both circle touch externally each other at point $P$.

Draw perpendicular taking $AP$ as base and vertex $P$.

$X{X}^{\prime }$ is the transverse common tangent between two circles.
