FIRST TANGENCY PRINCEPLE
Answer
Solution
FIRST TANGENCY PRINCIPLE
A single tangent line passes through any point
on a circumference that is perpendicular to the radius
defined by the centre and that point.
REMEMBER: How to draw a perpendicular line
to a given one, that passes through a point
BY USING SET SQUARES.
