Help me understand Geometry!?

Question

Ok! I'm just going into 9th grade this year!! I need major help understanding geometry! If you can just tell me things i need to know...help explain how to work out any problems..anything like that!! major appreciated...if you can help!

Answer 1

Here's the brief overview:

You have to know many terms: Coplanar, Postulates, Theorems, etc.

You must know several Postulates, several Theorems

How to identify Lines, Angles, Rays

How to apply Algebra in forms of Geometry

Using If-Then Statements

Properties of Algebra

Proving Theorems (Simple Proofs)

Angles/Perpendicular Lines/Basic Transversals

Parallel Lines

Parallel Lines in Polygons

Congruence in Shapes

Isosceles Triangle Theorem

Perpendicular Bisector

Properties of Parallelograms

Parallel Line Theorems

Special Parallelograms

Inequalities

Inverses/Contrapositives

Indirect Proofs

SAS Inequality Theorem

Ratio/Proportion

Similar Polygons

Pythagorean Theorem

Tangents/Arcs

Central Angles

Chords

Inscribed Angles

Here is the basic information. You may not learn all of it, but it's all there for your use.

Answer 2

just follow this link:

Answer 3

they teach you most of it there

but its pretty much all formulas that you have to memorize

like

rectangle:

A=lw

P=s1+s2+s3+s4



surface area of prisms and stuff too.

but they teach it to you there, so dont worry.

Answer 4

It's a lotta different shapes n stuff.

Answer 5

Geometry is not hard at all. This course should include finding area, volume, and surface area of many shapes. Dealing with angle measures, finding the missing angle measure of any shape, probability, trigonometry to find missing sides of triangles, right triangles, circles, Pythagorean theorem, constructing parallel and perpendicular lines using a compass and protractor, etc.

What would help you in Geometry would be knowing your basic terms such as points, lines, perpendicular, right angles, supplementary and complementary angles, parallel, etc.

I will tell you that Geometry can be tricky; make sure you read carefully and make sure you always ask for help when needed. Geometry is fun and interesting if you are willing to learn it.
