Geometry Concepts and Definitions

What is the definition of a point in geometry?

• A location with no size

• A dot with size

• A line with thickness

• A plane with boundaries

Which of the following best describes a line?

• A figure with no thickness extending infinitely

• A piece of a line with two endpoints

• A flat surface with boundaries

• A figure with thickness

What is a plane in geometry?

• A line with two endpoints

• A flat surface that extends forever

• A dot with no size

• A line with thickness

How are parallel lines characterized?

• Lines that are in different planes

• Lines that intersect at any angle

• Lines that intersect at 90 degrees

• Lines that never intersect and are in the same plane

What is the correct way to name a line segment?

• Using one point

• Using two endpoints

• Using three points

• Using a lowercase letter

When naming a ray, what is important about the order of the letters?

• The endpoint must be listed last

• The letters must be alphabetical

• The endpoint must be listed first

• The order does not matter

Which of the following is NOT a way to name an angle?

• Using just the vertex

• Using a number

• Using two points

• Using three points with the vertex in the middle

What does the term 'collinear' mean?

• Points that are on the same plane

• Lines that intersect

• Points that are on the same line

• Lines that are parallel

What is a bisector in geometry?

• A line that intersects at 90 degrees

• A figure that cuts another figure into two equal parts

• A point in the middle of a line segment

• A line that extends infinitely

How are skew lines different from parallel lines?

• Skew lines intersect at 90 degrees

• Skew lines are always perpendicular

• Skew lines are in different planes and never intersect

• Skew lines are in the same plane
