FLASHCARD QUESTION
Front
What is the measure of an arc in a circle?
Back
The measure of an arc is the degree measure of the angle formed by two radii that connect the center of the circle to the endpoints of the arc.
3.
FLASHCARD QUESTION
Front
How do you find the length of a tangent segment from a point outside the circle?
Back
The length of the tangent segment can be found using the Pythagorean theorem: if the distance from the point to the center is 'd' and the radius is 'r', then the length of the tangent 't' is given by t = √(d² - r²).

FLASHCARD QUESTION
Front
What is the relationship between the angle formed by two tangents from a point outside the circle?
Back
The angle formed by two tangents from a point outside the circle is equal to half the difference of the measures of the intercepted arcs.

FLASHCARD QUESTION
Front
What is the formula for the circumference of a circle?
Back
The circumference C of a circle is given by the formula C = 2πr, where r is the radius.
6.
FLASHCARD QUESTION
Front
How do you calculate the area of a sector of a circle?
Back
The area A of a sector is given by A = (θ/360) × πr², where θ is the angle in degrees and r is the radius.

FLASHCARD QUESTION
Front
What is the inscribed angle theorem?
Back
The inscribed angle theorem states that an angle inscribed in a circle is half the measure of the intercepted arc.
