Question

If BP PC, what is m BC? 60 90 180

Answer 1

Answer:

90

Step-by-step explanation:

BP PERPENDICULAR 2 PC SO

BC=90

Answer 2

Answer: 90

Step-by-step explanation:

Given: A circle with center P and B and C are two points on circle such that

BP is perpendicular to PC, it gives $\angle{BPC}=90^{\circ}$

We know that in a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc.

Therefore, the measure of  $\overarc{BC}$= Central angle made by  $\overarc{BC}$.

⇒ the measure of  $\overarc{BC}=90^{\circ}$
