Points X and Y are endpoints of a diameter of Circle W. Point Z is another point on the circle. Find the probability that XZY is a right angle.
Answer:
Probability=1
Step-by-step explanation:
<u>Theorem</u>
- If an Inscribed angle intercepts a semicircle, the angle is a right angle.
Given that X and Y are endpoints of a diameter of Circle W and point Z is on the circle's circumference.
I have prepared a diagram which is attached.
Then, XZY is an angle which intercepts a semicircle.
By the theorem above, XZY is a right angle.
Therefore, the probability that XZY is a right angle =1
