In a close figure it is the set of points inside the figure.
Yes they do. In geometry, pentacles (stars) have 10 points.
In coordinated geometry the points on a straight line will determine its equation.
geometry means lines, segments, and points!!
Alternate interior angles
Interior means within, like the interior of a house. If you are doing geometry, the interior of a shape is it's inside.
Geometry is the pure mathematics of points and lines and curves and surfaces.
Plenty, it is also a useful life skill to know geometry.
Two end points.
They are identifiers of position or location.
