SHS Geometry Unit 6 Test Review Part 1

Front

What is the formula for the area of a sector?

Back

Area = (θ/360) * π * r², where θ is the angle in degrees and r is the radius.

Front

What is a chord in a circle?

Back

A chord is a line segment with both endpoints on the circle.

Front

What is a diameter?

Back

A diameter is a special type of chord that passes through the center of the circle.

Front

What is the relationship between inscribed angles and intercepted arcs?

Back

Inscribed angles are half the measure of their intercepted arcs.

Front

What is a tangent line?

Back

A tangent line is a line that touches a circle at exactly one point.

Front

What is the difference between a secant and a tangent?

Back

A secant intersects a circle at two points, while a tangent intersects at only one point.

Front

What is the measure of a central angle?

Back

A central angle is equal to the measure of its intercepted arc.

Front

What is the relationship between the radius and diameter?

Back

The diameter is twice the length of the radius (d = 2r).

Front

What is the area of a circle?

Back

Area = π * r², where r is the radius.

Front

What is the circumference of a circle?

Back

Circumference = 2 * π * r, where r is the radius.
