Half of a square creates a 45-45-90 triangle. Half of a regular triangle creates a 30-60-90 triangle. ]]> 2017-02-16 21:04:23 UTC https://padlet.com/kernhighschooldistrict/t0pbz7953wqd/wish/154466210 532211 https://padlet.com/kernhighschooldistrict/t0pbz7953wqd/wish/154466222 There are two right triangles, one is a half of a square while the other is half of a triangle. The triangle that is half of a square has angles of 45-45-90 degrees, and the two shorter sides of it, the sides constructing the right angle, are equal, both are x. The one longer side is x√2. The other one, half a triangle, has angles of 30-60-90 degrees. The shortest side, the one constructing the 60 degree angle that isn't the hypotenuse, is x. The hypotenuse is 2x, and the side not yet mentioned is x√3. And remember: since both have a right angle, the Pythagorean Theorum can be applied.]]> 2017-02-16 21:04:28 UTC https://padlet.com/kernhighschooldistrict/t0pbz7953wqd/wish/154466222 532248 https://padlet.com/kernhighschooldistrict/t0pbz7953wqd/wish/154466228 45-45-90 is half a square
30-60-90 is half a triangle
