Question

The end points of diameter BD in a circle form an angle with point C. what is the measure of < BCD ?

Is it A- 180 degrees?
B- 90 degrees?
C- 60 degrees?
Or D- 45 degrees?

And why?

Answer 1

The answer is 90, this is because 180 would have been a straight angle, 60 would have been smaller, and 45 would have been way smaller

Answer 2

If BD is the diameter of the circle, and ∠BCD is an inscribed angle in the semicircle, then: B. m∠BCD = 90 degrees

Inscribed Angle of Semicircles

• A semicircle = 180 degrees.
• Diameter divides a circle into two semicircles.
• An angle that is inscribed in a semicircle = 90 degrees.

Therefore, if BD is the diameter of the circle, and ∠BCD is an inscribed angle in the semicircle, then: B. m∠BCD = 90 degrees
