In the figure for Exercises 7 to 16, O is the center of the circle. See Theorem 6.3.5.Given: A D = 10 , B C = 4 , A E = 7 Find: EC. To determine

To find:

The value of EC.

Explanation

The diagrammatic representation is given below,

Theorem:

1. If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord. Now compare the triangles ΔAED,ΔCEB

2. If two inscribed angles intercept the same arc, then these angles congruent. By using the above theorem mADE=mCBE

Vertical angles are congruent to each other. The angles that are opposite to each other are vertical angles.

By suing the vertical angle theorem to get the following,

mAED=mCEB

Since by Angle rule we conclude that

m
