Textbook Problem

For the circles described and shown, how many common tangents do they possess?a) Internally tangent circles b) Circles that intersect in two points To determine

a)

To find:

The number of common tangents in internally tangent circles. Explanation

Given:

The internally tangent circles.

Definition used:

A line, line segment, or ray that is tangent to each of two circles is a common tangent for the given circles. If the common tangent does not intersect the line segment joining the centers, it is a common external tangent.

Calculation:

Consider,

To determine

b)

The number of common tangents in circles that intersect in two points, Still sussing out bartleby?
