Unit 8 - Circle Theorems

Question 1

What is the theorem when you want to prove that chords of central angles are congruent if central angles are congruent

Answer 1

In a circle or congruent circles, congruent central angles create congruent chords

Question 2

What is the theorem you use when you have congruent chords and you want to prove that their central angles are congruent

Answer 2

In a circle or congruent circles, congruent chords have congruent central angles

Question 3

What is the theorem you use when you have congruent arcs and you want to prove that their chords are congruent

Answer 3

In a circle or in congruent circles, if arcs are congruent, then the chords that cut them off are congruent

Question 4

What is the theorem you use when you have congruent chords but you want to prove that their arcs are congruent

Answer 4

In a circle or in congruent circles, if chords are congruent, then they cut off congruent arcs
