## Kite

A Kite is a flat shape with straight sides. It has 2 pairs of equal-length adjacent sides. Characteristics of Kite Two pairs of sides Each pair is 2 equal-length sides that are adjacent The angles are equal where the 2 pairs meet Diagonals (dashed lines) cross at right angles, and one of the diagonals bisects … Continue reading "Kite"

## Linear Equations

A linear equation is an equation for a straight line. Different Forms There are many ways of writing linear equations. They usually have constants (like “3” or “c”) and must have simple variables (like “x” or “y”). The variables (like “x” or “y”) in Linear Equations do NOT have: Exponents (like the 2 in x2) Square … Continue reading "Linear Equations"

In the lesson below, you will learn about how to identify whether angles are adjacent. Definition Adjacent angles are 2 angles that have a common vertex & a common side. The vertex of an angle is the endpoint of the rays that form the sides of the angle. The common vertex and common side we mean here are … Continue reading "Adjacent Angles"

A fraction like 1/2 says we have 1 out of the 2 parts the whole is divided into. The top number is called numerator The bottom number is called denominator How to Add Fractions To add fractions there are Three Simple Steps: Make sure the bottom numbers (the denominators) are the same Add the top … Continue reading "Adding Fractions"

## Expanded Notation

Definition Expanded Notation is about Writing a number to show the value of each digit. Expanded Notation is shown as a sum of each digit multiplied by its matching place value (ones, tens, hundreds, etc.) Examples 1,234 = 1 × 1,000 + 2 × 100 + 3 × 10 + 4 × 1 98,765 = 9 × … Continue reading "Expanded Notation"

## Rational Function

Definition Rational Function is A function that is the ratio of 2 polynomials. It is Rational because one polynomial is divided by the other polynomial, like a ratio. (Note: the denominator cannot be zero.) Examples Learn More FOIL Method Counting Numbers Difference Multiplicative Inverse Definitions Index

## Alternate Exterior Angles

Definition When 2 lines are crossed by another line (Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. How to remember the angle pairs are on Alternate sides of the Transversal, and they are on the Exterior of … Continue reading "Alternate Exterior Angles"

## Alternate Interior Angles

Definition When two lines are crossed by another line (Transversal): Alternate Interior Angles are a pair of angles on the inner side of each of those 2 lines but on opposite sides of the transversal. How To remember: The angle pairs are on Alternate sides of the Transversal, and they are on the Interior of … Continue reading "Alternate Interior Angles"

## Composition of Functions

By combining these 2 function into 1 function, we have performed function composition, which is the focus of this section. Definition of Function Composition Function composition is a method to combine existing functions. Another method is to carry out the usual algebraic operations on functions, including addition, subtraction, multiplication, & division. We do this by … Continue reading "Composition of Functions"
