Chapter 3

today we needed a calculator.

at the beginning of class we looked at a picture of an acute triangle over an area of land. as a class we determined that someone such as a geographer or pilot would need to know the exact distances of this triangle between cities.

as a class we also decided that a triangle must be a right triangle to directly use triganometry ratios.

we then did the lacrosse problem on page 114.

We found that you must add a line segment to use trig ratios. We split the 6 ft line in half and joined it with the vertex across from it. We now formed two 90 degree angles. We then used sine to find the length of the unknown side. We continued by using trig and found that the goal was 5.43 feet. ... We were wrong. The answer is still unknown.

We then did our chapter 3 diagnostic test.

Next will be the girl who sits beside me.
