Geometry Final Exam Review 1

Front

What is the formula for the length of an arc in a circle?

Back

The length of an arc (L) can be calculated using the formula: L = rθ, where r is the radius and θ is the angle in radians.

Front

What is a secant in geometry?

Back

A secant is a line that intersects a circle at two points.

Front

Define an inscribed angle in a circle.

Back

An inscribed angle is formed by two chords in a circle which have a common endpoint. The vertex of the angle is on the circle.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of two perpendicular lines are negative reciprocals of each other. If one line has a slope of m, the other line's slope will be -1/m.

Front

How do you find the slope of a line given its equation in slope-intercept form?

Back

In the equation y = mx + b, m represents the slope of the line.

Front

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

Back

The area of a sector (A) can be calculated using the formula: A = (1/2)r^2θ, where r is the radius and θ is the angle in radians.

Front

What is the difference between a chord and a diameter?

Back

A chord is a line segment with both endpoints on the circle, while a diameter is a special type of chord that passes through the center of the circle.

Front

What is the central angle of a circle?

Back

A central angle is an angle whose vertex is at the center of the circle and whose sides are radii that extend to the circle.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the formula for the circumference of a circle?

Back

The circumference (C) of a circle can be calculated using the formula: C = 2πr, where r is the radius.
