This is a name for the middle number in a set of ordered numbers.
What is the median?
We use these units to measure angles?
What is degrees?
This is the speed your speedometer would read in mph if you were traveling down the highway at 25 m/s. Hint: 1 mile is approximately 1600 m.
What is 56 mph?
Shapes that satisfy the Pythagorean theorem
What is similar shapes?
This law states that the incoming angle of light on a surface relative to a normal must be equal to the outgoing angle.
What is the law of reflection?
This is the name for the spread of the data from the mean
What is standard deviation?
Use it when you want to know the opposite leg and you know the measure of the angle and hypotenuse.
What is Sine?
This is your reaction time if you were to drop a ruler, and it falls a distance of 20 cm before you catch it.
You must say your units!
What is 0.202s (or 202 ms)?
Pythagorean theorem can be used on this triangle
What is a right triangle?
This law relates angles and indices of refraction when light crosses a boundary between two different materials.

What is 42?
The key used to find the angle in the calculator
What is the inverse?
Colonel Stapp did another test run where he went from 0 m/s to 100 m/s in 15s. This was his acceleration.

When a set of numbers satisfy the Pythagorean theorem?
What is a Pythagorean triple?
This 330 million dollar mission resulted in catastrophic failure due to a unit conversion error.
What is the Mars Climate Orbiter?
This is the mean (or average) of Aaron's scores of 4, 5, 5, 2 and 4.

Light travels from air (n1 = 1.00) into an optical fiber with an index of refraction of n2 = 1.44. The incoming angle θ1 is 22o. This is the angle of refraction inside the fiber.
What is 15o?
