Des-mans Response

          The Des-man project was not bad. It was really hard for me to try and use restrictions but i did like making the face. It was funny trying to make the hair look like mine. But the equations were probably the hardest part of the whole project.

Chapter 8 Review

8.1 

This chapter I've learned about how to differentiate convex and concave polygons. I've learned about how to classify them within equilateral, equiangular, and by regular meaning it is both equilateral and equiangular.
                                                                              8.2                                                    

I've also learned how to measure the exterior and interior angles.

     m<1 + m<2. . . + m<n = (n-2) * 180  

8.3 

In this chapter I learned how to find the area of squares and rectangles.

     square - A=S(squared)

     rectangle A=(base)(height)

8.4

This chapter was all about finding the area of triangles, not that hard - it's the same formula just multiply it by 1/2.

     A=1/2(base)(height)

                                                                               8.5

In this chapter we explored more about finding areas... Only now it's the area of parallelograms.

     A=(base)(height)

8.6

Again we learn about areas, this time it is area of trapezoids. 

     A= 1/2(height)(base 1 + base 2)

8.7

This chapter we slightly changed (still finding areas) we learn about the circumference and area of a circle. 

     A= (Pi)(Radius - Squared)

     C=(Pi)(Diameter) or C=(Pi)(Radius - squared) 

7.1 - 7.3 Study Guide

7.1

Ratios:

• A Ratio is a comparison of a number a and a nonzero number b using division. They can be written in Four different ways. Ratios are usually written in Simplest form. 

Proportions:

• An Equation  that states two ratios are equal is called a Proportion. In a proportion the numbers b and c are called the Means of the proportion. The number a and d are called the Extremes of the proportion.  

Cross Product Property:

• In a proportion the product of the extremes  is equal to the product of the means. 

7.2

Similarity:

• Two figures that have the same Angles are Congruent  AND corresponding side lengths are Proportional THEN two polygons are Similar Polygons.  

Scale Factor:

• If the two polygons are similar THEN the ratio of the lengths of two Corresponding sides is called the Scale Factor. 

Determining Similarity:

1. Check that corresponding angles are Congruent.
2. Check whether corresponding side lengths are Proportional.

7.3

Angle-Angle Similarity Postulate:

• If two angles of one triangle are Congruent to two angles of another triangle THEN the two triangles are Similar

Postulate vs. Theorem

• Come up with THREE things that you believe strongly                                                                                                                                                                                                                   1. Basketball is fun (Theorem)

Many watch it on tv.

Many people play it.

People dream about making it to the nba.

Because you make money.                                                                                                                                                                                                                                                                                                        2. Soccer is a great sport (Theorem)

The most watched sport on tv.

People want to become the best. 

They want to make money.

Better life.

           3. People love food (Theorem/Postulate)

People eat it. 

God put it on the earth to eat.  

You need it to live.

Nutrition. 

Keeps you healthy. & It taste really good.

• Create a statement and reason
• Decide if this belief is a theorem or postulate 
• write a response to each

1. The difference between a theorem and postulate is that a theorem can be proven by facts and a postulate is just accepted and cannot be proven. It just is. In my life theorems and postulates just model my actions. Its just what i did.
