A theorem in geometry states that the measure of an inscribed angle is half the measure of its
intercepted arc. In the figure, ZC intercepts arc AB and AB is the diameter of the circle,
Which equation is a step in showing that mZC = 90°?

Answer:

The  correct option is C

Step-by-step explanation:

From the question  the slope  AC is evaluated as

            [tex]m_1 = \frac{b-0}{a- (-c)}[/tex]

            [tex]m_1 = \frac{b}{a+c}[/tex]

And  the slope of line  CB is mathematically evaluated as

        [tex]m_2 = \frac{0-b}{c-a}[/tex]

        [tex]m_2 = \frac{b}{c-a}[/tex]

Now for lines that are perpendicular to each other then the product of their slope should be equal to  -1

So if  [tex]m ZC[/tex] [tex]= 90^o[/tex]

Then

     [tex]m_ *m_2 = -1[/tex]

i.e  

      [tex][\frac{b}{a+ c} ] [\frac{b}{a-c} ] = -1[/tex]
