True/False: The sine of an angle can be greater than 1.

• True, we don't know which leg is greater/smaller.

• False, the legs are always shorter than the hypotenuse, so the leg/hypotenuse will always be less than 1.

True/False: The tangent of an angle can be greater than 1.

• True, when the opposite leg is longer than the adjacent leg.

• False, the opposite leg is always shorter than the adjacent leg.

What is wrong with the student's trig equation?

• Nothing, it is correct.

• The triangle is not a right triangle.

• The student should have used sine.
