Equalateral Triangles and 30-60-90s

What is an equilateral triangle?






How can we find the height of these three equilateral triangles? 



What observations can we make about the equilateral triangles?
 Equilateral Triangle
* All sides Equal
* < sum is 180
* all <'s = 60
* if you cut in half 2 rt triangles
* neg space makes a square
* no hypot.
* no rt. < so no pythog.
* a 2 = b 2 = c 2
* just find one side length to find perimeter


What generalizations can we make?



HW:Due Tomorrow
On a 30, 60, 90 triangle (right triangle),  describe the relationship between the side length in generalizable terms and why is makes sense.

L-5 Same page as reflection

If you have a 30-60-90 and this side length is 36.What are the other side lengths?

18 and 18 square root of 3.
