INTRODUCTION Technology was used by all people all over the world. In this modern world, technology is always present. Many people consider technology is useful to people for it help the people to do things easier and accurately. Technology is very popular to us. One of its popularity is using technology in mathematics by solving mathematics problems. Microsoft Mathematics, Cabri II Plus, Cabri 3D, Microsoft Excel, SPSS, and etc. are examples of programs that will help people especially the students in answering the problems and helping us to construct figures accurately. Nowadays, we people in this generation are actually lucky because we enjoy those services offered to us especially the Microsoft Mathematics was made for free for all the students around the world and by just typing the equation and then press the enter key Viola! The answers and the procedure are already given. Technologies in Mathematics not just only give us the answer immediately and its procedure but it allow us to formulate our own conjectures to the different figures that we have constructed, it help us to be an observant. Especially in the Cabri you can construct at the same time you can formulate your own conjecture(s) about what have you constructed. By those available programs that will help us in our studies, whether you are student, researchers and the like, with these we should avail those programs so that we can do things accurately and in easiest way, as well as with those programs we are able to explore new things.

Centers of The Triangle

Polygons divided into three Parts

 Polygons are divided into three parts.As you can see, the more sides of the polygon, the angle in the center is decreasing. While in the circle was not depending on the sides because the arc of the circle is compose of infinitely many lines.

Using Cabri II plus
