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.
