In Exercises 46 to 49, prove the stated theorem.If two secant segments are drawn to a circle from an external point, then the products of the length of each secant with the length of its external segment are equal. See Figure 6.51 on page 303. To determine

To find:

To prove the following stated theorem,

“If two secant segments share the same endpoint outside a circle, then the product of the length of one secant segment and the length of its external segment equals the product of the length of the other secant segment and the length of its external segment.”

Explanation

Given that tangent EB¯andED¯ are secant segemnts.
