What is the point of concurrency where the perpendicular bisectors of a triangle intersect?

Back

Circumcenter

Front

How do you find the arc length of a circle?

Back

Arc Length = (θ/360) * 2πr, where θ is the angle in degrees and r is the radius.

Front

Convert 510° to radians.

Back

17π / 6

Front

What is the measure of the missing angle in a right triangle if one angle is 45°?

Back

45°

Front

How do you calculate the balance in an account with compound interest?

Back

A = P(1 + r/n)^(nt), where A is the amount, P is the principal, r is the rate, n is the number of times interest is compounded per year, and t is the number of years.

Front

What is the definition of a circumcenter?

Back

The circumcenter is the point where the perpendicular bisectors of a triangle intersect, and it is equidistant from all three vertices.

Front

What is the formula for converting degrees to radians?

Back

Radians = Degrees × (π/180)

Front

What is the formula for finding the area of a sector?

Back

Area = (θ/360) * πr², where θ is the angle in degrees and r is the radius.

Front

What is the definition of an incenter?

Back

The incenter is the point where the angle bisectors of a triangle intersect, and it is equidistant from all three sides.
