Chapter 6&10: eXPLORING QUADRILATERALS
ISOSCELES TRAPEZOID:
Is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides, making it automatically a trapezoid
REGULAR TRAPEZOID: is a trapezoid whose non-parallel sides are congruent (of equal length).
QUADRILATERAL:a quadrilateral is a polygon with four sides (or edges) and four vertices or corners. Sometimes, the term quadrangle is used, by analogy with triangle, and sometimes tetragon for consistency with pentagon (5-sided), hexagon (6-sided) and so on.
RECTANGLE: is any quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°).
RHOMBUS: is a simple (non-self-intersecting) quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.
SQUARE: a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or right angles)
KITE:a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.
DIAGONAL: is a line joining two nonconsecutive vertices of a polygon or polyhedron.
PARALLELOGRAM: a parallelogram is a simple (non self-intersecting) quadrilateral with two pairs of parallel sides.
AREA: is the quantity that expresses the extent of a two-dimensional surface or shape, or planar lamina, in the plane.
POLYGON: is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit.
RADIUS:the radius of a circle or sphere is the length of a line segment from its center to its perimeter.
REGULAR POLYGON: is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
