When do we use normal trigonometry versus inverse trigonometry?
Normal trigonometry is used to find missing sides when given an angle. Inverse trigonometry is used to find missing angle measures given at least two sides.

Which of the following is not a valid way to check if a quadrilateral is a parallelogram?
a. Find the slopes of the diagonals to see if they are perpendicular
b. Find the slope of each side to see if the opposite sides are parallel
c. Use the distance formula to see if the opposite sides are congruent
d. Use the midpoint formula to see if the diagonals bisect each other
e. All of the above are valid ways to check if a quadrilateral is a parallelogram
Choice A does not give us enough information to determine if it is a parallelogram.

a. Inscribed angles have a vertex on the center of a circle and a measure twice that of a corresponding central angle.
b. Inscribed angles have a vertex on the circumference of a circle and a measure twice that of a corresponding central angle.
c. Central angles have a vertex on the center of a circle and a measure twice that of a corresponding inscribed angle.
d. Central angles have a vertex on the circumference of a circle and a measure twice that of a corresponding inscribed angle.
