Overview of Geometry Concepts
Geometry is one of the oldest studies in the world, with beginnings in ancient Mesopotamia, Egypt, and the Indus Valley around 3000 B.C. In your Geometry tutoring, you may cover how to determine answers for questions of size, shape, and relative position of figures within the properties of space. Because geometry is such a visual section of math, it is easy to use it to describe things everyday.
Length, Area & Volume
Can you tell me how long that football field is? How many people will fit in a pool before there isn't any more room for more people? How many gallons does your fishtank hold? In your tutoring session, your online geometry tutor can help you understand geometric formulas for lengths, areas and volumes so that you can always figure out the answer to these kinds of questions.
The length of an object is the distance between its ends, as measured from end to end. When someone asks you how long your pencil is, you can whip out your ruler and tell them exactly how many inches, centimeters, or even millimeters it is! Because length is a one-dimensional measure, it is easy to see and understand. To measure area or volume, we need to move into the second and third dimension.
Area is a measure expressing the size of a part of a surface. "Surface area" is the sum of all the areas of the exposed sides of an object. There are different formulas for different shapes, so you need to know what formula you need an area from before you can begin. Say we want the area of a rectangle that is 3 inches by 5 inches. For a rectangle we multiply the length by the width to find the area, which would be 15 inches in this case. Of course, if you want the area of a triangle or a trapezoid, you need a different formula!
We use circumference to find the area of a circle in geometry, and it is the distance around a closed curve. I know, I know...how can you find the area of something when it doesn't have sides like a triangle or rectangle? Geometry can help you figure that out. The circumference of a circle can be calculated from its diameter by using this formula:
c = TT x d
or, substituting the radius for the diameter: c = 2TT x r
where d is the diameter of the circle, r is the radius, and TT (the Greek letter pi) is the infinite constant 3.141 592 653 589 793...
The volume of a solid object is the three-dimensional concept of how much space it occupies, expressed in numbers. One-dimensional figures, (such as a line on a paper), and two-dimensional shapes, (such as the rectangle we talked about), have no volume in a three-dimensional world. Say you want to find the volume of water that your square fish tank can hold. In this case we would use the formula for a cube, s3, to find the volume. If s = the length of a side, then s times s times s would give you the volume of your fishtank. Every three-dimensional shape has a volume formula, so if you are unsure about what to use and when, your expert Geometry tutor can help walk you through it and make you the top of your class in geometry!
Pythagorean Theorem
Ok, we've all heard of it, but what is it and how is it useful? The famous Pythagorean theorem is a relation of the three sides of a right triangle. What's with the name? Well, it's named after the Greek mathematician Pythagoras, who is credited with its discovery and proof, however other mathematicians in other parts of the world were also working on it.
Pythagoras' theorem is this: In any right triangle, the area of the square whose side is the hypotenuse, the side opposite the 90 degree angle (c), is equal to the sum of the areas of the squares whose sides are the two legs that meet at the 90 degree angle (a & b). If we write it in "mathspeak" it looks like this:
a2 + b2 = c2
This equation provides a simple relation among the three sides of a right triangle so that if the lengths of any two sides are known, the length of the third side can be found. This simple relation is also know as the law of cosines, a topic that can be found in our trigonometry section. So we have a nifty equation, but what else does this theorem give us? Pythagoras and his Pythagoreans were also able to come up with the idea that irrational numbers, such as the square root of five, can be constructed. So mathematicians have been able to build on this theorem to come up with other ideas that can help us get further in things like calculus, physics, and even the engineering that was used to build your computer!
Does all this "mathspeak" sound like gibberish to you? Don't worry! By using online tutoring with your Tutorzilla geometry tutor or ap geometry tutor, you can expand your knowledge for finding the circumference and area of a circle, area of a triangle, and the volume of a cylinder, sphere, and a pyramid.
Once you have mastered the techniques of geometry, you can move forward with an online trigonometry tutor.
