Measuring Segments Opener

Front

What does the midpoint of a segment do?

Back

The midpoint of a segment splits the segment into 2 equal pieces.

Front

What are congruent segments?

Back

Congruent segments are segments that are exactly the same length.

Front

How do you find the length of a segment?

Back

To find the length of a segment, subtract the coordinates of the endpoints and take the absolute value.

Front

What is the formula for the midpoint of a segment with endpoints (x1, y1) and (x2, y2)?

Back

The midpoint is ((x1 + x2)/2, (y1 + y2)/2).

Front

If segment AB has endpoints A(2, 3) and B(4, 7), what is the length of segment AB?

Back

The length of segment AB is √((4-2)² + (7-3)²) = √(4 + 16) = √20 = 2√5.

Front

What is the definition of a segment?

Back

A segment is a part of a line that has two endpoints.

Front

What does it mean for segments to be equal?

Back

Segments are equal if they have the same length.

Front

What is a line segment?

Back

A line segment is a straight line that connects two points.

Front

What is the distance formula used for?

Back

The distance formula is used to calculate the distance between two points in a coordinate plane.

Front

What is the significance of the midpoint in geometry?

Back

The midpoint is significant because it helps in dividing segments into equal parts, which is essential in various geometric constructions.
