#### About 10 Maths Exercise 10.2

Most of the questions in Exercise 10.2 are based on Tangent ⊥ Radius and then solve it by Pythagoras Theorem. Question no. 8 and 9 are based on “Tangents drawn from same external points are equal”. Question no. 11 is same as question 8, only one or two more steps are required. Question no. 13 is based on question no. 9. Question no. 12 is the most important question as it is asked in CBSE board exams several times.
