• 35

• 42

• 70

In the diagram, a, b, c, and d represent the lengths of the segments that make up the chords. What is the relationship between the lengths of the segments?

• a + b = c + d

• a = b = c = d

• a * b = c * d

• a * c = b * d

• A
• B
• C
• D

What is the formula to calculate the length of a chord in a circle?

• length = 2 * radius * sin(angle/2)

• length = 2 * radius * cos(angle/2)

• length = 2 * radius * tan(angle/2)

• length = radius * sin(angle)
