**How many common internal tangents can be drawn to each pair of circles in exercise 1 above ?**

**a.** The final answer is $2.$

**b. **The final answer is $1.$

**c. **The final answer is $0.$

**d. **The final answer is $0.$

**e. **The final answer is $0.$

**f. **The final answer is $0.$

The figure is given.

A tangent is internal tangent if the intersection of tangent and line joining centres of two circles is empty.

Now, we apply our concept that is-

A tangent is internal tangent if the intersection of tangent and line joining centres of two circles is empty.

Given figure has two internal tangents as shown below.

Therefore, the answer is $2.$

The figure is given.

A tangent is internal tangent if the intersection of tangent and line joining centres of two circles is empty.

Now, we apply our concept that is-

Given figure has two internal tangents as shown below.

Therefore, the answer is $1.$

The figure is given.

Now, we apply our concept that is-

Given figure has no internal tangents.

Therefore, the answer is $0.$

The figure is given.

Now, we apply our concept that is-

The figure has no internal tangents.

Therefore, the answer is $0.$

Now, we apply our concept that is-
