Geometry and measurement : Module 21 Years : PDF Version of module. The material in this module is a continuation of the module, Parallelograms and Rectangles , which is assumed knowledge for the present module. Thus the present module assumes:. Logical argument, precise definitions and clear proofs are essential if one is to understand mathematics.

In Euclidean plane geometry , a quadrilateral is a polygon with four edges or sides 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. The word "quadrilateral" is derived from the Latin words quadri , a variant of four, and latus , meaning "side". Quadrilaterals are simple not self-intersecting or complex self-intersecting , also called crossed. Simple quadrilaterals are either convex or concave.

Year 10 Interactive Maths - Second Edition. A quadrilateral is a closed plane figure bounded by four line segments. For example, the figure ABCD shown here is a quadrilateral. A line segment drawn from one vertex of a quadrilateral to the opposite vertex is called a diagonal of the quadrilateral. The theorems we have proved can be used to prove other theorems.



Quadrilateral

We think you have liked this presentation., A quadrilateral from the Latin "quadri", meaning "square" and "latus", meaning "side" is a four-sided polygon a polygon is a flat, enclosed shape with multiple straight edges.

Quadrilaterals: Classification

A polygon is a flat surfaced shape. A quadrilateral is a four-sided polygon. A rectangle has two axes of line symmetry. The diagonals of a rectangle are equal and bisect each other. Bisect means cuts in half.

A quadrilateral is a polygon with four sides. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel. A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rhombus is a parallelogram with four congruent sides. The plural of rhombus is rhombi. I love that word.
