We have been using the Sin, Cos, and Tan formulas in class and on the homework for the last few classes. The trig formulas are really interesting, because hey allow you to find a side length of a right triangle, when you only know the measures of a side and two angles. Its also cool that for eah angle measure, the ratio is always the same, no matter how big or small the triangle is. This makes finding the ratios so much easier!

We learned the formulas to find the area and circunfrance of a circle. We also learned a lot about the radius and diameter of a circle , and their special properties, and their relationships with pi. As well as learning about circles, we learned how to find the area of regular polygons, trapezoids, kites, and rhombuses. We also had a test at the end of the week. I thought it was going to be a lot harder than it actually was. Article posted May 21, 2012 at 07:57 PM GMT-5 • comment • Reads 43

The triangle either has to have two 45 degree angles, and a right angle; or it can have 30, 60, and 90 degree angles. In the 45, 45, 90 triangle; the hypotenuse is the length of one of the legs times the square root of two. in the 30, 60, 90; the long leg is the short leg times the square root of three, and the hypotenuse is twice the length of the short leg.

The theorem is cool, because you can use it for a lot of different purposes. Since a lot of different shapes are made up of triangles, like parallelagrams, you can use the pythagorean theorem to help you find the area or perimiter of those shapes.

Sometimes the square roots of numbers are never ending, unrepeting decimals; so we use simplified radicals to write them instead. Radicals can sometimes take a while to simplify, but i think that once i memorize a lot of the perfect squares, it will be much easier.

This makes the line of reflection very similar to a line of symmetry. Reflections can sometimes be difficult, because ou have to reflect each point seperately, and if you mess one up, the whole thingis wrong; although it usually easy to notice.

Translations are when the hape is moved, dialations are when the shape changes size, and are when the shape is rotated around one point.

We also learned a lot of new theorems that have to do with the different quadrilaterals. It was interesting how a lot of the properties and characteristics of the quadrilaterals, were also theorems that we could prove. Article posted March 26, 2012 at 07:58 PM GMT-5 • comment • Reads 59
