## Solving SSA Triangles

SSA (Side, Side, Angle) is when we know 2 sides and 1 angle that is not the angle between the sides. How to solve an SSA triangle ? First, use Law of Sines to calculate one of the other two angles. Then, use the three angles add to 180° to find the other angle. Finally

## Vertical Angles

Definition Vertical Angles are the angles opposite each other when two lines cross In this case, “Vertical” means they share the same corner point (Vertex), not the usual meaning of up-down. Example a° and b° are vertical angles. Vertical Angles are Congruent Angles The interesting thing here is that vertical angles are congruent angles: a°

## Logarithmic: Definition, Functions & Rules, Examples

Definition of Logarithmic Functions Logarithmic and exponential function has close relation. It is because logarithmic inverse of exponential function. Any exponential function can be changed to be logarithmic function and any logarithmic function can be changed to be exponential function. For example there is exponential function x = ay, so the logarithmic function is alog

## Even and Odd Numbers

Even Numbers Any integer that can be divided exactly by 2 is an even number. The last digit is 0, 2, 4, 6 or 8 Example: −10, -4, 0, 8, and 32 are all even numbers Odd Numbers Any integer that cannot be divided exactly by 2 is an odd number. The last digit is 1, 3,

## Cardinal and Ordinal Numbers Chart

Definitions A Cardinal Number is a number that says how many of something there are, such as 1, 2, 3, 4. An Ordinal Number is a number that tells the position of something in a list, such as 1st, 2nd, 3rd, 4th. Most ordinal numbers end in “th” except for: one ⇒ first (1st) two

## Set Symbols

Set Symbols – A Set is a collection of things, usually numbers. We can list each element or member of a set inside curly brackets like this: {2, 4, 6, 8, … } Three dots means goes on forever (infinite) Common Symbols Used in Set Theory Symbols save time and space when writing. Here are

## Negative Exponents

Definitions Exponents are also called Powers or Indices The exponent of a number says how many times to use the number in a multiplication. General form of exponent an tells you to use a in a multiplication n times Those are positive exponents How About Negative Exponents? Dividing is the inverse (opposite) of Multiplying. A negative exponent

## Frequency Distribution

Frequency is how often something occurs. Definition of Frequency Distribution We can make a Frequency Distribution table by counting frequencies. So, Frequency Distribution means: values and their frequency (how often each value occurs). Learn More Stem and Leaf Plots Percentage Change Quartiles Discrete and Continuous Data Data Index

## Cross Multiply

To cross multiply is to go from this: To a × d = b × c How Does it Work? Multiplying the top (numerator) and bottom (denominator) of a fraction by the same amount doesn’t change its value. So, To cross multiply: Multiply the top and bottom of the left side fraction by the bottom

## Continuous Function: Definition & Examples

Definition of Continuous Function  Function describe as a relation of each value from the first set that is associated exactly one value from another set. Function has many types in mathematics. One of them is continuous function. Continuous function is one of topics in calculus. Continue means unbroken. Continuous function is a function that has
