Textbook Problem

In Exercises 23 to 25 , complete a paragraph proof. Given: Tangent A B ¯ to ⊙ ο at point B m ∠ A = m ∠ B Prove: m B D ⌢ = 2 ⋅ m B C ⌢ To determine

To find:

The prove mBD=2mBC.

Explanation

Calculation:

Given,

mA=mB.

To prove: mBD=2mBC.

Since, Tangent AB¯ to ο at point B.

A is a tangent-secant angle, mA=mBDmBC2.

B has the vertex on the circle and is a chord-tangent angle, mB=mBC2.

Given,

mA=mB

Substitute the values of mA and mB in mA=mB
