2. Introduction
Trigonometry is the study of mathematic relationships involving length, height and angles of triangles. Trigonometry was founded by Hipparchus of Nicaca, a Greek mathematician who created the first trigonometric table. Hipparchus eas born about 190 B.C. Today trigonometry used on every day and it impacts many fields on a daily basis, some of these fields are construction, architecture and physics to name a few.

3. Construction To measure the area of a field or loft of land.
To calculate the height, length and width of a bridge, wall, ramp or building.
To measure and determine the angles and volumes needed to properly lay the foundation of a house in order To make it level.
To measure the correct length and width of a room to properly lay tiles.
To measure and calculate roof inclination, along with the height and width of the support beams.
Construction
Construction is a field that uses trigonometry to calculate measurements everyday. Some of the ways trigonometry is used in construction are listed at the side.

4. Goal: to shed light on the importance of construction
We chose construction over all the other fields that use trigonometry functions because we believe many people over look the importance of mathematics used in this field. Many people including ourselves forget that without construction we would not have buildings, homes, bridges and subway stations which are necessary things need in our daily lives . Without buildings and subway stations we would not have shelter and transportation .

5. Problem
The length of run is 12 inches and the length of the total rise is 6 inches . What is the length of total span and the rafter length of based on the information given above.

6. Solution: Steps taken to Solve problem
The problem to the right is asking us to find the rafter and the total span. The line place in the middle lets us know that both triangles are symmetrical to eat other. If the run on one side is 12inches the run on the other side is 12 inches as well. So the total span would be 24 inches. Now let's find the rafter length.... We have two sides but we are missing the hypotenuse Rafter length, and we're going to do that by applying Pythagorean theorem theory(A^2+B^2=C^2). SOLVING
