HISTORY OF POLYGONS Polygons have been known since ancient times. The regular polygons were known to the ancient Greeks, and the pentagram, a non-convex regular polygon (star polygon), appears on the vase of Aristophonus, Caere, dated to the 7th century B.C.[citation needed] Non-convex polygons in general were not systematically studied until the 14th century by Thomas Bredwardine.[20] In 1952, Shephard generalized the idea of polygons to the complex plane, where each real dimension is accompanied by an imaginary one, to create complex polygons.[21] [pic] The historical image of polygons 1969 SOME PICTURES OF POLYGONS METHODS OF FINDING AREA OF TRIANGLE Method 1: h b If you know base (b) and height (h) of the triangle, the following formula can be applied. Area =  ½ x b x h Method 2: a c b If you know three sides (a, b and c) of the triangle, Heron’s Method can be applied. s = (a+b+c) / 2 Area =( s (s-a) (s-b) (s-c) Method 3: a ( b If you know twoShow MoreRelatedUsing Math Vocabulary With Intentionality While Incorporating A Comprehensive Vocabulary Program1538 Words   |  7 PagesStudents will use math vocabulary with intentionality while incorporating a comprehensive vocabulary program that will be updated and utilized throughout the year as a main component of my instruction. Throughout the ELL certification program, vocabulary has been consistently emphasized as an invaluable strategy for the teaching and learning of ELL students. Although this has been stressed, it has not become a focus in my instruction; my plan is to develop a structure that will ensure that vocabularyRead MoreDifferent Kinds Of Energy And Which Ramp Will Be Faster1183 Words   |  5 Pagespotential energy, and Mechanical energy. I would also like to find out if the tallest or the lowest ramp will be faster. I will also tell you what my hypothesis is and the materials I will be using. Plus ill add a statistical question about what ramp is faster. I will also be talking about math and how to find the missing angle in a trangle. There are a few different kinds a energy and they are kinetic energy, potential energy, gravitational potential energy, elastic potential energy, chemical potentialRead MoreComparison Of My Math Strengths And Weaknesses866 Words   |  4 Pages My Math Strengths and Weaknesses As I am approaching the end of my educational career, it is time for me to evaluate how well I will do teaching a subject I struggled in elementary school, math. Math is a subject I had a love hate relationship with. I liked it when I was good and hated it when I struggled. I noticed this pattern not only because of my abilities, but also of my teacher’s abilities to teach the subject. My goal is not to be a genius in math but I do want to be able to helpRead MoreUsing Internet Sites With Sixth Graders1653 Words   |  7 PagesUsing Internet Sites with Seventh Graders My idea for having my seventh graders do a research project came from the session of my Walsh University class in which we were given the assignment of researching information on anything we were interested in with our electronic devices. This sparked an idea: How much more interested could my students be, than being given the opportunity to select their own topic to research? I knew I would be able to let them do their research at school on chromebooksRead MoreWhy Is A Manipulative?1223 Words   |  5 Pagesfractions bars and algebra tiles to name a few. These manipulatives are in the form of Java or Flash applets, a web base technology. Normal playing cards have so many uses in teaching mathematical lessons. When teaching your students how to add, subtract, sort, compute or compare numbers, using a deck of cards gets the students working with numbers while playing a game. There are two advantages of using a deck of cards as a hands-on manipulative: First advantage; cards are inexpensive, canRead MoreProgressivism : Teaching As A Future Educator896 Words   |  4 Pagesengage the students and ensure that what they are learning will stick with them and add to their educational goals. Throughout my education, I remember how the majority of my teachers were always the main focus of the classroom environment. I had to make sure I paid close attention in hopes of being able to understand what was being taught to me. There were times that I felt rushed to understand things such as math problems and before I knew it, I was being tested on it. With the progressivism styleRead MoreJob Report1125 Words   |  5 PagesDeveloper? †¢ A Senior Developer tends to oversee the development of current project’s they tend to be the leader of the project sometimes they have to perform coding assignments set by the company, Depending on the size of the project if they’re short on time the senior developer will have to write more or less code since they normally work in teams and do little bits for each project and piece them all together.

I worked with a wide spectrum of individuals, from fellow peers to Vice Chancellors. Several of the activities included tutoring, lab work and presentations. I believe, these works are the initial stones that laid the ground work for my current path to a graduate degree in the biomedical sciences. While at the University of Arkansas at Pine Bluff, one place I volunteered my time was within the STEM program. This program held SaturdayRead MoreMarketing Plan For A Business Plan1159 Words   |  5 Pagespopulation-wise. For instance if you are a College Graduate planning to offer Math tutoring to students in your community, then your business scope will be small and so will your startup costs. In fact, you could probably launch your business for next to nothing. You could market via word-of-mouth and do your tutoring at home, in the school library or even online via Skype. If on the other hand, you plan to expand your scope to tutoring Math, Science and English to any students within your city, then your costsRead MoreMusic Lessons Improve Life Essay1540 Words   |  7 Pagesall play the piano. Do they do it for fun or is it something else? Some recent studies have shown that there are improvements that people haven’t considered before. â€Å"The studies have shown th at children in music lessons scored higher in English and math than students who had no music lessons at all†¦Ã¢â‚¬  (Baedeker). So with lessons in music, students could do better in life than without music lessons. With improved academics, they are able to solve problems better and get to college and thus get better
