The perimeter is the sum of all the
sides of a geometric figure.
Angles
are formed by the union of two straight line
segments, from a common point, called the
vertex of the angle. They are classified indo:
The area of a geometric figure
expresses the size of a surface.
Thus, the larger the surface of the
figure, the greater its area.
Plane geometry
Plane geometry
studies figures
that have no
volume
Point
Since it has no dimension. Points
determine a location and are
indicated with capital letters.
Straight
The straight line, represented by a
lowercase letter, is a one-
dimensional unlimited line (it has
length as a dimension) and can
appear in three positions:
horizontal, vertical, slanted
Lines that do not have a point in
common are called parallel lines.
Line segment
It is limited because it corresponds to the
part between two distinct points and has no
end.
Layout
It corresponds to a two-dimensional flat
surface, that is, it has two dimensions:
length and width. It is on this surface that
geometric figures are formed.
