Question

The endpoints of diameter in a circle form an angle with point C. What is the measure of angle BCD?

Answer 1

90 degrees

Step-by-step explanation:

Please note that whenever a triangle is inscribed in a circle and one side of the triangle is a diameter of the circle as in the given figure, then the angle that is opposite the diameter of the circle is a right angle;

`\therefore\angle BCD=90^(\circ)`
