  1. #1 False
    A triangle has three angles, which add up to 180 degrees. The two right angles use all that up.
    #2 True
    #3 True
    #4 False
    Just draw any obtuse triangle. If two of the legs happen to be equal, stretch one of them a little.
    #5 True
    #6 False.
    Draw a tall skinny isosceles triangle. Only two sides have to be equal for an isosceles triangle.
    #7 True (see #5)
    #8 False
    A right triangle has a 90-degree angle. The other two angles must add up to 90 degrees, making them both acute angles.
    #9 False
    In fact, NO right triangle can be equiangular (see #1)
    #10 True
    Not just two, but all three sides are equal.
    #11 False (#4 again?)
    #12 False
    All three sides might be equal.
    #13 False
    Only right triangles have a hypotenuse
    #14 True
    #15 True

    Looks like you have some serious reviewing ahead.
