To draw:two tangents from point A ,
Explanation of Solution
Given:
A is any point outside the
Following are the steps to draw two tangents from point A .
Consider a circle with center O .
Consider a point A outside of the circle.
Join the line OA .
Bisect the line OA . Line of bisector will meet with line OA at Q .
Draw a circle of radius AQ with center at Q . This new circle will cut the original circle at T and V .
Join AT and AV . AT and AV are the required tangents.
The construction is shown below:
