Sine: A trigonometric function, only used in right triangles, that is equal to the ratio of the side opposite of the given angle to the hypotenuse. Symbol: sin
sin(63)=AB/AC
I chose this term because it is one of the three right triangle trigonometry functions. It allows you to find the angle measure if given the measures of the hypotenuse and the side opposite to the angle. It also works the other way around because you can use the angle measure and hypotenuse to find the measure of the side opposite to the given angle or you can use the opposite and the given angle to find the measure of the hypotenuse. That's why I thought this would be good to know.

Cosine: A trigonometric function, only used in right triangles,that is equal to the ratio of the side adjacent to the given angle measure to the hypotenuse. Symbol: cos
cos(72)=EF/DF
I chose this term because it's one of the right triangle trigonometry functions. It can be used to find the missing angle measure when given the hypotenuse and the side adjacent to the angle measure. It can also be used to find the hypotenuse if given the angle measure and the side adjacent to the angle. Finally it can be used to find the adjacent side length when given the hypotenuse and the angle measure. It can be used for many things and that's why I chose this term.

Tangent: A trigonometric function, only used in right triangles, that is equal to the ratio of the side opposite of the given angle to the side adjacent to the given angle. Symbol: tan
tan(36)=XY/YZ
I chose the term tangent because it is one of the right triangle trigonometry functions and is one of the most used. It can be used to find the measure of an angle when given the side opposite to the angle and the side adjacent to the angle. It can be used to find the side opposite to it when given the measure of the angle and the side length of the adjacent side. It can also be used to find the adjacent side when given the length of the opposite side and the measure of the angle. This can be used to find many things and is very common so I chose to use this in the visual glossary.

Apothem: A line segment from the center of a regular polygon bisecting one of the sides perpendicularly.
Symbol:a
Symbol:a
OP is the apothem of the regular octagon.
Apothem is important in finding area of regular polygon. The apothem can also be used to find the radius of a figure and half the side length of a figure. It can be very useful when the side length isn't provided for you. That's why I decided to use apothem in the visual glossary.

Scale Factor: The term that describes the ratio of enlargement or reduction.
Symbol: No symbol
Symbol: No symbol
The scale factor of the rectangles is 1:3
I chose scale factor because it is important in deciphering whether to figures are similar. Similar figures have one ratio which is the scale factor. You can find the scale factor and use it to find missing variables. It's truly important.

Angle of Elevation: The angle formed by the line of sight and a horizontal plane for a point above the plane.
Symbol: no symbol
Symbol: no symbol
Angle ABC is and angle of elevation.
Knowing what the angle of elevation can be very useful. It can help you in trigonometry real world applications. Usually the given angle is the angle of elevation.

Angle of Depression: The angle formed by the line of sight and a horizontal plane for a point below the plane.
Symbol:no symbol
Symbol:no symbol
Angle DAB is the angle of depression. Even though it isn't always direct in trigonometry, the angle of depression is very important. Since it's the alternate interior angle of the angle of elevation. Knowing this can help you to understand that it can help set up a proper picture for you.
Geometric Mean: The average which indicates typical value of a set of numbers. The geometric mean of two positive numbers is the square root of their product.
The geometric mean of 2 and 8 is 4.
Knowing how to create a proportion to calculate geometric mean is important in RABBIT theorem and HEARTBEAT theorem. It helps you find x with just two values.
