Front

What is the distance formula used to find the distance between two points P(x1, y1) and Q(x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the definition of coplanar points?

Back

Coplanar points are points that lie on the same plane.

Front

How do you find the length of a line segment on a number line?

Back

Subtract the coordinates of the endpoints: Length = |x2 - x1|.

Front

What is the definition of the intersection of two lines?

Back

The intersection of two lines is the point where they cross each other.

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same straight line.

Front

What is the formula for the midpoint of a line segment between points A(x1, y1) and B(x2, y2)?

Back

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

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

How do you determine if three points are coplanar?

Back

Three points are coplanar if they lie on the same plane or can be connected by a single flat surface.

Front

What is the definition of a point in geometry?

Back

A point is a precise location or position in space, usually represented by a dot.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.
