Geometry Semester Review Topic 1

Front

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

Back

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

Front

Given points A(-1, 7) and B(11, -1), find the midpoint of segment AB.

Back

Midpoint = (5, 3)

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

If the distance between points A(2, 3) and B(5, 7) is calculated, what is the result?

Back

Distance = 5

Front

What does it mean for points to be coplanar?

Back

Points are coplanar if they lie on the same plane.

Front

True or False: Points E, J, and G are coplanar.

Back

True

Front

What is another name for a line segment?

Back

A line segment can also be referred to as a 'line segment' or 'line segment AB'.

Front

What is the definition of a line in geometry?

Back

A line is a straight one-dimensional figure that has no thickness and extends infinitely in both directions.

Front

What is the definition of a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

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.
