Review Book “Mathematics for Junior High School”

QUALITY

Generally, quality of all part of this book is very good and interesting to read.

 Viewed in terms of paper
The paper has good quality. Paper that is used is quite thick and its color are light, so each writing looked clear. When we read it, we will not be bored quickly. Because of the thick paper, it cause ink that is used is not perforated.

For the important things is used more than one color to differentiate. Because of the different color, we easily find the important points from the main criticism that discussed.
 Viewed in terms of coloring
The book is printed in various kind of colors which is very clearly and with gradiation color, so it attracts attention from the students to read that book.
 Photo images that have
The display of the photo like photo paper so we like to see the original photo. It can attract readers to read.
 Example problem
Example problem can make us understand in each chapter that is presented. The example problems can represent the material that is discussed.
 Exercise
The exercises that have are sufficient to know our competence after we read and learn the subject. With these exercises that have, we can value our understanding.
 Quality of printing
It is printed with a very neat and organized so that the posts which are very neatly printed and does not fall apart.

Bertolak Belakang : For behind
a different angle of each corner is not a zero angle or straight, said, for behind each other if and only if the second leg-foot angle is formed two pairs of lines of opposite rays

Sejajar : Parallel

Two lines g and h are represented in parallel with each other "g ∥ h"

Parallel
Buag two lines that do not have a share point

Saling Asing : Foreign mutual
Two circle each other are two strangers who do not have the loop point associate.
Two circle each other foreigners outside the loop are the two mutually foreign areas not beririsan
Two circle each other in a strange circle of two foreigners in the area of circle are a load area in the other circle

Limas

Many areas of the region limited by a polygon and the triangular areas that alasnya coincide with the polygon-side, the dots are peak coincide in a point that is located outside the polygon.
Polygon layer called the area, the area called the triangle-hand upright, dots coincide is called a peak point

Sebangun : Uniform
Two uniform polygon said what if there is a correspondence and a mutual berkorespondensi is congruent
For example two of the triangle there is correspondence. Both said the triangle is uniform if and only if the corners of each other berkorespondensi congruent and proportional berkorespondensi the side.
Can be written

Kerucut : Cone

Build a space limited by cone-shaped field and a field perpendicular to the cone axis field.
Cone does not have a rib, the distance from the top of the field to load the base field is called a high cone.
Cone terpancung: A cone of terpitong by a field parallel to the field of alasnya
The parallel field is cut by a cone-shaped field circle, hereinafter referred to as the field on the cone terpancung.

INTRODUCE TO ENGLISH ONE

Last week was the frist time we join English class. The teacher is Dr. Marsigit. He has gone very much to foreign. For this time, He told me about his experience. He has gone twice to British, Thailand, Japan and Australia for the third.

In the frist week, he asked me to make blog. It’s will good function for me making task especially English Language. He also told me to surfing his blog in http:/powermathematics.blogsport.com, he advice me to be follower at http:/marsigitenglish.blogsport.com. Fornutetly, I make a troble. I think that it’s can do it with first postig. I think that he asked me to posting it with the first meet and twice. Unfortunetly, he wan not sad. He give us motivasion to make a good work in the next time. Thank’s Mr.Marsigit.
