Silverio Triangle

Vicky and me created a triangle on cardboard. First we had to draw the triangle on patty paper and then bisect the angles. Then we traced the triangle into the cardboard and we label the vertex and the midpoint. We colored the triangle then we had to balance the triangle in a pencil.

MY GOALS

This summer I feel like I improve alot in diffrent stuff because Geometry was new to me. But I still little bit of help in diffrent stuff

Babylonians Math

Babylonians used clay tablets to do math in them. The clay tablets included fractions, algebra, quadratic and cubic equations. It also had the Pythagorean theorem, and the calculation of Pythagorean triples. Also the Babylonian tablet gives an aproximation to the square root of 2 to 6 decimal places. The Babylonian mathematical system was sexagesimal. Babylonian mathematicians also developed algebraic methods of solving equations. The Babylonians also used geometry and trigonomaetry.

Silverio's Fibonacci Numbers

The red and the blue lines show sets of spirals.

Fibonacci numbers are a sequence where the first two terms are both 1. Fibonnaci numbers came from Arabia. We use this numbers in math. Fibonacci numbers are also found in nature. They are found in apples too. The Golden Ratio is much harder. Ancient Greeks thought a most appealing rectangle was one with the proportion of width/length=length/length+width.

Numbers By Silverio

We watch a movie on July 16 this was a movie about a guy that committed crimes and the FBI was in look for him. The FBI used help from a guy that used math to track down were he lives and were he works his results dont give the adress. The guy was found at work and was shot by an FBI agent. We used the computers to construct points of origins, triangle, and perpendicular bisectors. This movie shows how geometry is used in other ways.

Silverio's Geometry Art

This is a picture of a colorful astrid and a knot design

Silverio's Tetrahedron

On July 13,2007 we made a tetrahedron. The materials we used were clear straws, yarn, and needles. All of the sides of the triangles are equal. This triangles in the tetrahedron have a centroid,orthocenter,incenter,and a circumcenter.

Silverio's 2 time winning airplane

This is an airplane that I made on July 6,2007 we had four competitions I won 2 of them for furthest and straightest. Next time I would like to win the competition for the highest and the facyest.

Silverio's Rotational Symmetry

This is a picture of a checkers piece. If you rotate this piece 120,240,or 360 degrees it will still look the same. This is a five fold rotational symmetry.
