Unit 1 HW1: Points, Lines, and Planes

Front

What is a point in geometry?

Back

A point is a specific location in space that has no size or dimension.

Front

How many points are typically represented in a geometric figure?

Back

The number of points can vary; in the provided example, there are 8 points.

Front

What is a line in geometry?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions.

Front

How many lines are typically represented in a geometric figure?

Back

The number of lines can vary; in the provided example, there are 3 lines.

Front

What is a plane in geometry?

Back

A plane is a flat two-dimensional surface that extends infinitely in all directions.

Front

How many planes are typically represented in a geometric figure?

Back

The number of planes can vary; in the provided example, there are 5 planes.

Front

What is the intersection of two planes?

Back

The intersection of two planes is a line where they meet.

Front

What is the intersection of lines a and b in the provided example?

Back

The intersection of lines a and b is point W.

Front

What does it mean for two lines to intersect?

Back

Two lines intersect if they cross each other at a single point.

Front

What is the notation for naming a line?

Back

A line is typically named using two points on the line, such as line EF.
