Ex 10.1,2
Fill in the blanks
(i) A tangent to a circle intersects it in _____ point (s).
One point
Note only there can be one tangent at point P i.e. tangent XY
If we try to make more than one line at point P example AB,
it becomes a secant (as it intersects at more than one point)
Ex 10.1,2
Fill in the blanks
(ii) A line intersecting a circle in two points is called a _____.
Secant
Ex 10.1,2
Fill in the blanks
(iii) A circle can have _____ parallel tangents at the most.
Two
Note only two tangents are possible AB and XY
CD is not a tangent it is a secant as it intersects at 2 points
Ex 10.1,2
Fill in the blanks
(iv) The common point of a tangent to a circle and the circle is called _____ .
