Circle Theorems and Tangents

This video tutorial explores additional circle theorems, building on previous lessons. It covers the tangent and radius theorem, the equal tangents theorem, and the alternate segment theorem. The video includes explanations, examples, and practice questions to reinforce understanding. It concludes with a review and a preview of the next lesson on intercepting chords.

What is the angle between a tangent and a radius of a circle?

• 120 degrees

• 90 degrees

• 60 degrees

• 45 degrees

If two tangents are drawn from a point to a circle, what can be said about their lengths?

• One is double the other

• They are unequal

• They are perpendicular

• They are equal

What is a tangent in the context of circle theorems?

• A line that intersects the circle at two points

• A line that is inside the circle

• A line that touches the circle at only one point

• A line that is parallel to the circle

Which theorem states that the angle between a tangent and a chord is equal to the angle in the alternate segment?

• Chord Theorem

• Tangent-Radius Theorem

• Equal Tangents Theorem

• Alternate Segment Theorem

In the alternate segment theorem, which angle is considered?

• The angle next to the tangent

• The angle furthest away

• The angle at the center

• The angle on the same line

How many theorems related to circles were covered in this video?

• Four

• Three

• Two

• One

What should you do if you find the alternate segment theorem tricky to remember?

• Forget about it

• Write it down somewhere visible

• Ask a friend

• Ignore it

What is the focus of the upcoming part three of the video series?
