Geometry Fundamentals

Flashcards created from lecture notes covering basic geometric definitions including rays, segments, lines, midpoints, planes, parallel, intersecting, skew lines, and space.

What geometric figure begins at one point and extends infinitely in one direction?

A ray

What is a segment?

A part of a line or ray that is between two points

How many end points do rays, segments, and lines have?

A ray has one end point, a segment has two end points, and a line doesn't have any end points

What is a midpoint?

The exact middle of a segment

What is true about the halves of a segment when it is bisected?

Their halves are equal (congruent)

What is a plane?

A flat surface that extends infinitely

What are parallel lines?

Lines that extend infinitely without crossing

What are intersecting lines?

Lines that cross because they are not parallel

What is space?

A set of all points in three dimensions

What are skew lines (Kew)?

Lines that will never intersect in space and are not parallel

Are parallel lines always coplanar?

Yes, parallel lines are always coplanar
