Circle Theorem Review

Which segment is the diameter?

• DE

• BO

• AO

• AB

If DE is a chord, what do we think the definition of a chord is?

• the same as a radius

• the same as a diameter

• a line segment connecting two points on the circumference of a circle

• a line segment with one point on the circumference and the other point at the center

What is this an example of?

• radius

• diameter

• secant

• tangent

If a radius is 5 cm then what is the length of the diameter?
