Answer 2

Fill in the blanks:

(i) The common point of a tangent and the circle is called POINT OF CONTACT .

** There is only one tangent at a point on the circle.

 

(ii) A circle may have TWO parallel tangents.

**A circle can have maximum two parallel tangents which can be drawn to the opposite side of the centre.

(iii) A tangent to a circle intersects it in ONE points(s).

** A tangent to a circle is a line that intersects or touches the circle at only one point.

(iv) A line intersecting a circle in two points is called a SECANT .

(v) The angle between tangent at a point on a circle and the radius through the point is RIGHT ANGLE (90°) .

**The tangent at any point of a circle is perpendicular to the radius through the point of contact.
