Geometry Basics (Naming/ SAP/ MP/ Dist)

Front

What is the definition of a midpoint?

Back

A midpoint is a point that divides a line segment into two equal parts.

Front

How do you find the midpoint of two points (x1, y1) and (x2, y2)?

Back

The midpoint M is given by M = ( (x1 + x2)/2 , (y1 + y2)/2 ).

Front

What are collinear points?

Back

Collinear points are points that lie on the same line.

Front

What is a plane in geometry?

Back

A plane is a flat surface made up of points that has two dimensions and extends without end.

Front

What is the notation for a ray?

Back

A ray is represented by two points, with one point as the endpoint and the other extending infinitely in one direction.

Front

What are endpoints in geometry?

Back

Endpoints are the points at either end of a line segment or ray.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is the definition of a vertex?

Back

A vertex is a point where two or more lines or edges meet.

Front

What is the formula for the distance between two points (x1, y1) and (x2, y2)?

Back

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.
