Question

A theorem in geometry states that the measure of an inscribed angle is half the measure of its

Answer 1

Answer:

The first option is the correct option

Step-by-step explanation:

From the question  the slope  AC is evaluated as

            $m_1 = \frac{b-0}{a- (-c)}$

            $m_1 = \frac{b}{a+c}$

And  the slope of line  CB is mathematically evaluated as

        $m_2 = \frac{0-b}{c-a}$

        $m_2 = \frac{b}{c-a}$

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

So if  $m ZC$ $= 90^o$

Then

     $m_ *m_2 = -1$

i,e  

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