A point is a vertex
A dot.
There are typically three words in geometry that are undefined. The first is "point." A point has no dimension, length, width, or thickness. The second is "line." A line has no thickness and goes on indefinitely in both directions. The third undefined term is "plane." A plane has no thickness and has no boundaries.
a point, line and plane
a point
We use words we know to define new terms in geometry. The words point, line and plane have no other words in geometry to describe them They are the building blocks.
Do it!
Point, line and plane ARE terms from geometry.
A point is a vertex
Tangent, in geometry, is used to describe when figures have only one point in common. In Trig. tangent is applied to triangles.
1 use is to describe a point in the plane. Say you have x=2 and y=11. and can be z=2+i11.
Parallel lines are lines in the same plane that never cross. Also, in the most common geometry (i.e., Euclidian geometry), the distance between the two lines is the same at any point.
