Unit 2A - Basics of Geometry Vocabulary

What is the definition of 'Point'?

• A location in space that is represented by a dot and has no dimension.

• Has one dimension: represented by a line with two arrowheads, but extends without end.

• A flat surface made up of points that has two dimensions and extends without end and is represented by a shape that looks like a floor or wall.

• Consists of two endpoints and all the points between them.

What is the definition of 'Line'?

• Points that lie on the same line.

• Has one dimension: represented by a line with two arrowheads, but extends without end.

• Line segments that have the same length.

• A point, ray, line, line segment, or plane that intersects the segment at its midpoint.

What is the definition of 'Plane'?

• A) A flat surface made up of points that has two dimensions and extends without end and is represented by a shape that looks like a floor or wall.

• B) Consists of two endpoints and all the points between them.

• C) Points that lie on the same line.

• D) Line segments that have the same length.

What is the definition of 'Line Segment'?

• Consists of two endpoints and all the points between them.

• Points that lie on the same line.

• A location in space that is represented by a dot and has no dimension.

• Has one dimension: represented by a line with two arrowheads, but extends without end.

What is the definition of 'Collinear'?

• Points that lie on the same line.

• Line segments that have the same length.

• A point, ray, line, line segment, or plane that intersects the segment at its midpoint.

• A flat surface made up of points that has two dimensions and extends without end and is represented by a shape that looks like a floor or wall.

What is the definition of 'Segment Bisector'?

• A point, ray, line, line segment, or plane that intersects the segment at its midpoint.

• Consists of two endpoints and all the points between them.

• Points that lie on the same line.

• Line segments that have the same length.

What is the definition of 'Congruent Segments'?

• A) Line segments that have the same length.

• B) Points that lie on the same line.
