- Ali, your test grade was a B+
- you made a very common mistake! on your 30, 60, 90 triangles, you used the formula for 45, 90 triangles.
- how am i supposed to remember that
- please see Mrs . Iannuzzi for your test grades
- for 30, 60, 90 triangles, the short side is X, the long side is Xroot3 and the hyp. is 2X.
- for 45, 90 triangles, the two short sides are X and the hyp. is Xroot2.
- one way you can remember which goes to which, is think that the 30, 60, 90 triangles have 3 different angles so it has 3 different measurements!
