Geometry Chapter 1 Review

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If m∠K = (3x + 3)° and m∠L = (10x - 4)°, how do you find the measures of ∠K and ∠L?

Back

Set up the equation (3x + 3) + (10x - 4) = 90, solve for x, then substitute back to find m∠K and m∠L.

Front

What is the midpoint of a line segment?

Back

The midpoint is the point that divides the segment into two equal parts.

Front

What is the midpoint formula?

Back

The midpoint formula is ((x1 + x2)/2, (y1 + y2)/2) for two endpoints (x1, y1) and (x2, y2).

Front

What is the distance formula?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²) for two points (x1, y1) and (x2, y2).

Front

What is the measure of angle K if m∠K = 24°?

Back

m∠K = 24°.

Front

What is the measure of angle L if m∠L = 66°?

Back

m∠L = 66°.

Front

What is the definition of an endpoint in geometry?

Back

An endpoint is a point at the end of a line segment.

Front

How do you calculate the distance between two points?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the significance of the slope in geometry?

Back

The slope represents the steepness of a line and is calculated as rise/run.
