Angle Bisector

"An angle is formed by two rays with a common endpoint. The angle bisector is a ray or line segment that bisects the angle, creating two congruent angles. To construct an angle bisector you need a c ...

Linear Inequalities

"If we want to solve for or describe a region in a coordinate plane, we can use linear inequalities. Linear inequalities give us a set of solutions as opposed to just one solution. You can solve linea ...

Alternate Interior Angles

"Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs (f ...

Alternate Exterior Angles

"Alternate exterior angles are formed by a transversal intersecting two parallel lines . They are located "outside" the two parallel lines but on opposite sides of the transversal, creating two pairs ...

Line Segments

"A line segment is part of a line, has fixed endpoints, and contains all of the points between the two endpoints. One of the most common building blocks of Geometry, line segments form the sides of p ...

Age Word Problems

"Setting up a system of equations is usually effective when solving age word problems involving the ages of two people. Knowing how to solve systems of equations is necessary to solve these types of p ...

Adjacent Angles

"Adjacent angles share a side and a vertex. If angles only share a side but not a vertex, they are not adjacent. Adjacent angles can also be described as "next to" or "side-by-side" angles." Fuente: B ...

Additive Inverse

"Inverses, like the additive inverse or multiplicative inverses, are important for understanding how to cancel terms when solving for variables in equations and formulas. When a number is added to its ...

Absolute Value Equations

"Solving for a variable in absolute value equations follows different rules than when we solve multi-step equations. When solving absolute value equations, most of the time we get more than one possi ...

Absolute Value

"Sometimes we need to use only positive numbers, and the absolute value is a useful tool for this purpose. When you see an absolute value in a problem or equation, it means that whatever is inside the ...
