Early trigonometry The ancient Egyptians and Babylonians had known of theorems on the ratios of the sides of similar triangles for many centuries. But pre-Hellenic societies lacked the concept of an angle measure and consequently‚ the sides of triangles were studied instead‚ a field that would be better called "trilaterometry".[6]The Babylonian astronomers kept detailed records on the rising and setting of stars‚ the motion of the planets‚ and the solar and lunar eclipses‚ all of which required

covered the application of geometry using chapters 10 and 11. We analyze geometric definitions and relationships including congruency‚ triangle properties and triangle inequalities. Circles and arcs are another concept studied as well as proportions between parallel lines and congruent segments. This helped me to study similarity and proportions between polygons and triangle. At the end of week three I was able to specify locations using coordinate geometry‚ describe spatial relationships using coordinate

Pyramid In geometry‚ a pyramid is a polyhedron formed by connecting a polygonal base and a point‚ called the apex. Each base edge and apex form a triangle. It is a conic solid with polygonal base. A pyramid with an n-sided base will have n + 1 vertices‚ n + 1 faces‚ and 2n edges. Platonic Solids A Platonic solid is a solid such that all of its faces are congruent regular polygons and the same number of regular polygons meet at each vertex. Tetrahedron In geometry‚ a tetrahedron is a polyhedron composed

Over the duration of six weeks‚ we worked in a math unit called "Shadows." During the unit‚ we worked to solve the unit problem‚ which was to find a formula for how long a shadow was. When first given the unit problem‚ I considered it a simple task but soon after I realized there were many steps and ideas that needed to be learned before the unit goal could be reached. Throughout these six weeks‚ we learned about trigonometry‚ similarity‚ patterns‚ congruency‚ and using angles to solve problems.

312. As indicated in the first figure‚ the man is walking along a path from point A to point D‚ followed by point C and point B. The distance we are looking for is represented by AB. As shown in the second figure‚ ABE and CBF are isosceles right triangles. Since BC = 2‚ CF = 1 2 1 2 . Since AE = BE‚ BE = 3 + 1 2 also. Therefore‚ AB = 2 • AE 1 = 2 • 3 + 2 = 2 + 3
