If AB is the tangent to the circle at E, what is the length of AB?

Question 3 :
<img style='object-fit:contain' src='https://teachmint.storage.googleapis.com/question_assets/cbse_ncert/61b19bcd273b230584979a1c.JPG' /> The above image shows that a circle and two lines parallel to a given line AB is such that one is a tangent and the other , a secant to a circle , i.e , the line CD is the tangent at point M while the line EF is the secant . Is this statement true ?

Question 4 :
The common point of a tangent to a circle and the circle is called point of contact.

Question 5 :
A tangent to a circle intersects it in how many point(s)?
