• 
• 

Match the following terms to their definition

• A line that intersects the circle once

• Diameter

• A line that intersects the circle twice

• Tangent Line

• The longest chord, goes through center

• Secant Line

• Segment with both endpoint on the circle

• Chord

Match the following problems to the theorem that applies

• If a line is tangent, then right angle

• 
•

Select the way(s) we can prove a right angle exists to prove a line tangent to a circle

(Multiple Select)

• By Pythagorean Theorem. If we have a right triangle, then we have a right angle

• By Interior Angle Sum. If all three angles in a triangle add to 180, then we can find the third angle given two

• By Secant Lines.

  If a line intersects the circle there is a right angle.

• By Angle Bisectors,

  Cutting angles in half can prove the right angle exists
