Draw a RIGHT triangle. Select an angle that is not the right angle, mark it, then label the correct sides as: hypotenuse, opposite, and adjacent.
Pick a group to steal points from.
The sum of the acute angles in a right triangle.
What is a 90°?
A circle with a radius of 1, centered at the origin of a coordinate plane.
What is a unit circle?

Draw a triangle and place all relevant information at the appropriate place.
Pick a group to steal points from.
The ratio of the opposite side to the hypotenuse.
What is sine?
Steal points from the group to your right.
The measure of the size of an angle based on the radius of a circle.
What is a radian?
Steal points from the group to your left.
The Law of Sines.
What is:
a/sin(A) = b/sin(B) = c/sin(C)
sin(A)/a = sin(B)/b = sin(C)/c
Pick a group to steal points from.
A TV has a diagonal length of 39 inches. If the height of the TV is 15 inches, what is the width of the TV?
36 inches.
Pick a group to steal points from.
Pythagorean triple that is NOT 3,4,5.
(5, 12, 13) ; (7, 24, 25) ; (8, 15, 17) ; (9, 40, 41) ; (11, 60, 61) ; (12, 35, 37)...
Pick a group to steal points from.
The Triangle Inequality Theorem.
What is the theorem in which the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side of a triangle?
Pick a group to steal points from.
The Law of Cosines (for missing side).
What is:
a2 = b2 + c2 - 2bccos(A)
b2 = a2 + c2 - 2accos(B)
c2 = a2 + b2 - 2abcos(C)
Steal points from the group to your left.
Milo is looking at the top of an 84 foot tall lighthouse at an angle of elevation of 58°. If Milo is 6 feet tall, how far is he standing from the base of the lighthhouse? (Can round to 2 decimal places).
Milo is standing 48.74ft away (exact: 48.73980ft)
