2. IN ORDER TO I DENTIFY THE DIFFERENT KIND OF QUADRILETERAL THROUGH POWER POINT PRESENTATION;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

3. quadrilateral is any shape the has four sides. Outlined below are four definitions that are good to always keep in mind when working with quadrilaterals

4. Diagram 2 is a Venn Diagram, which uses overlapping circles to show relationships between groups of objects. Quadrilaterals is the most general group and can be divided into parallelograms and trapezoids. Parallelograms can then be further divided into rectangles and rhombuses. Rhombuses and rectangles can each be further divided into squares. Although not shown in this particular diagram, trapezoids can be further divided into isosceles trapezoids.

5. Parallelogram: Opposite sides are equal in length and parallel to each other. Opposite angles are congruent. Rhombus: A type of parallelogram. But each of the sides are equal in length. Square: A type of parallelogram. But all four sides all equal in length and each of the four angles are 90 degree angles. Rectangle: A type of parallelogram. But each of the four angles are 90 degree angles. Trapezoid: Contains one set of opposite parallel lines. Isosceles Trapezoid: A trapezoid with equal length in legs and equal measurements of base angles.

6. There is also a theorem in geometry that tells us that in all quadrilaterals, the sum of the measures of the angles is 360 o. This can be used in many situations, including problems where you need to find the measures of angles. 1. Problem: Find the measure of angle x.

7. Similar polygons are polygons for which all corresponding angles are congruent and all corresponding sides are proportional. Example:
