Exploring Points, Lines, and Planes in Geometry

What is a point in geometry?

• A line with two endpoints

• A flat surface with thickness

• A location in space with no size

• A location in space with size

How is a line represented in notation?

• With a capital letter

• With a lowercase letter or two points with a line above them

• With three capital letters

• With a cursive letter

What is a plane in geometry?

• A flat surface with thickness

• A flat surface containing an infinite number of lines

• A location in space with no size

• A line with two endpoints

What happens when two lines intersect?

• They form a plane

• They intersect at a point

• They intersect at a line

• They do not intersect

What does collinear mean?

• Lying on the same line

• Lying on the same plane

• Intersecting at a point

• Intersecting at a line

What is a line segment?

• A line that extends forever

• A flat surface with no thickness

• A part of a line with two endpoints

• A part of a line with one endpoint

How is a ray different from a line segment?

• A ray has one endpoint and extends infinitely in one direction

• A ray has two endpoints

• A ray is a flat surface

• A ray has no endpoints

What are parallel lines?

• Lines that lie on the same plane but do not intersect

• Lines that intersect at 90 degrees

• Lines that intersect at a point

• Lines that lie on different planes

How are perpendicular lines represented in notation?

• With a lowercase letter

• With a capital letter

• With a small perpendicular angle

• With a small parallel symbol

What indicates that two lines are perpendicular in an image?

• A small square label at the corner of the intersection

• A small parallel symbol

• A lowercase letter

• A capital letter
