GEOMETRY

GEOMETRY
The mathematical study of the properties, measurement, and relationships of points, lines, planes, surfaces, angles, and solids. We have divided the content on this page into the same "chapters" that are in your textbook.

Chapter 7 - Right Angles and Trigonometry Chapter 8 - Quadrilaterals

**Chapter 7 - Right Angles and Trigonometry**

 * Pythagorean Theorem**
 * Review the basic concepts with a video at Khan Academy. Lots of examples will make sure you know how to recognize a hypotenuse; understand where a, b, and c are in //a//2 + //b//2 = //c//2 ;and start to simplify square roots in your answer. Part II of the video is here and introduces 45-45-90 triangles. Listening to the narrator think out loud will help you know what questions to ask yourself when you are solving problems on your own.
 * Quiz yourself at Mathopolis. If you get an answer wrong, the site will show you the correct steps.


 * Converse of the Pythagorean Theorem**
 * Learn how to determine whether a triangle is a right triangle with a lesson on Winpossible, which includes a video demonstration and the ability to text for help.


 * Sine, Cosine, and Tangent Ratio**
 * A video at Khan Academy reviews the Soh Cah Toa method. Part II of the video is here.
 * Quiz yourself at Mathopolis. Remember to pay attention to which side is the opposite and which side is adjacent!


 * Solving Right Triangles**
 * If you know the length of two **sides** of a triangle, you can figure out the length of the remainig side by using the Soh Cah Toa Method. This page at Math is Fun shows you how.

**Chapter 8 - Quadrilaterals**
Learn about the properties of different four-sided shapeas at Math Is Fun. It includes a "family tree" so you can figure out the answer to questions like "is a square a rhombus?" You can also play with interactive quadrilaterals to see how the angles and diagonals change.


 * Find angle measures in polygons**
 * Absorblearning.com gives a clear, concise overview of how this works.


 * Basic Shapes**

rectangle
A parallelogram with four right angles

//**Example:**// 

square
A rectangle with 4 equal sides

//**Example:**// 

triangle
A polygon with three sides

//**Examples:**// 

acute triangle
A triangle in which all three angles are acute

//**Examples:**// 

circle
A closed plane figure with all points on the figure the same distance from the center

//**Example:**// 

GEOMETRY
Geometry is the study of: Recently new Apps and websites have made it possible for students to learn Geometry in an easier way. Geometry Pad is a App for Apple Devises that assist students in various ways. In addition i have found interactive website like that allow the students and teacher be able to utilize the text book from a computer. Supporting materinals that are embeded into the site allowing the teacher and students to learn through varoius souces like [|youtube]and interactive games, and puzzles directly on the site.
 * # The branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.
 * 1) A particular mathematical system describing such properties: "non-Euclidean geometries". ||

Another very usefull educational site that can assist students and teachers is [|Kuta Software] This site has all kinds of wonderfull, usefull online tools that helps and reenforces geometry. Prezi Online Math Tutor give an oview of what geomtry is and in addition it has games and tutors on the site.
