Here is the information I gave you yesterday:

Triangles:

no sides the same: scalene

2 sides the same: isosceles

all (3) sides the same: equilateral

Since a triangle's angles must add up to 180, if there are 2 45 degree angles, the one left must 90 degrees. Do you know what a triangle is called if it has a 90 degree angle?

This should be enough information to help you.
