SHS Unit 6 Test Review Part 3

Front

What is the measure of a full circle in degrees?

Back

360°

Front

What is the formula to find the length of an arc?

Back

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

Front

How do you find the measure of a missing arc if you know the other arcs in a circle?

Back

Subtract the sum of the known arcs from 360°.

Front

What is the relationship between the central angle and the arc length in a circle?

Back

The arc length is directly proportional to the central angle.

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2πr, where r is the radius.

Front

How do you solve for x in an equation?

Back

Isolate x on one side of the equation using inverse operations.

Front

What is the measure of an angle in a triangle if the other two angles are known?

Back

The measure of the third angle = 180° - (sum of the other two angles).

Front

What is the definition of a segment in geometry?

Back

A segment is a part of a line that is bounded by two distinct endpoints.

Front

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

Back

Area = πr², where r is the radius.

Front

What is the definition of an arc in a circle?

Back

An arc is a portion of the circumference of a circle.
