Unit 1 Flashcard D (Principles)

Front

What is the midpoint formula for two endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

What is the midpoint between the points (3, -1) and (7, -5)?

Back

(5, -3)

Front

The middle of a line is called the _______________.

Back

Front

What is the center of the line segment connecting M(3, -1) and N(7, -5)?

Back

(5, -3)

Front

What does the term 'endpoint' refer to in geometry?

Back

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

Front

What is the definition of 'slope' in a line?

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

How do you calculate the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the significance of the midpoint in geometry?

Back

The midpoint divides a line segment into two equal parts.

Front

If the endpoints of a line segment are (2, 4) and (6, 8), what is the midpoint?

Back

(4, 6)
