NGEC Flashcards
Also known as Tetragon or Quadrangle, is a general term for a four- sided polygon.
Quadrilaterals
These are line segments joining any two adjacent vertices (corners).
Side
Is an angle form between two adjacent sides.
Interior angles
It is the distance between two parallel sides of the quadrirateral.
Height
This is the bottom side that is perpendicular to the altitude.
Base
This is the line segment joining any two non- adjacent vertices.
Diagonal
has two pairs of parallel sides.
Parallelogram
has only one pair of parallel sides.
Trapezoid
does not have any pair of parallel sides.
Trapezium
are special types of parallelogram
Rectangle, Rhombus, and Square
- Is essentially a parallelogram in which the interior angles are all right angles.
Rectangle
is a parallelogram in which all the sides are equal.
Rhombus
is a two dimensional closed figure bounded by straight line segments.
Polygon
is one of the line segments that makes up the polygon.
Side or Edge
the point where the side meet.
Vertex
the angle formed by two adjacent sides outside the polygon.
