Question: What is the relationship between the angles subtended by the same arc at the center and at the circumference?

Options:

1. They are equal
2. The angle at the center is twice the angle at the circumference
3. The angle at the circumference is twice the angle at the center
4. They are complementary

Correct Answer: The angle at the center is twice the angle at the circumference

Solution:

The angle subtended at the center is always twice the angle subtended at the circumference by the same arc.
