It's not enough to just consider the number of sides in a quadrilateral, we must also consider the congruence of sides, the types of angles formed, and the presence of parallel or perpendicular lines. Using a square as an example, we...

Systems of two linear equations in two variables can have a single solution, no solutions, or an infinite number of solutions. This chapter explains why.

This tutorial is an introduction to solving nonlinear equations with Python. The solution to linear equations is through matrix operations while sets of nonlinear equations require a solver such as Scipy optimize fsolve to...

👉 Learn about parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry, parallel lines are identified by two...

👉 Learn how to label points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A point is...

In this video, the teacher explains how to determine if a point is a solution to multiple equations and how to approximate the X coordinate of the intersection of two lines by observing their graphs. The teacher emphasizes the importance...

In this lesson, students will learn how to prove the concurrency of medians theorem using parallel lines and properties of similar triangles. They will explore the concept of medians, midsegments, and midpoints in triangles, and...

👉Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes the each of the equation in the system true. To solve a system of equations by...

👉 Learn all about solving and graphing compound inequalities. An inequality is a statement in which one value is not equal to the other value. A compound inequality is a type of inequality comprising of more than one inequalities. To...

The video explains how to represent both short-run and long-run macroeconomic equilibrium in an AD/AS (Aggregate Demand/Aggregate Supply) diagram. It covers key terminology and concepts associated with the different curves involved in...

👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry,...

In this video, we provide examples of finding the probability of certain events given specific conditions, such as the probability of survival on the Titanic based on passenger class. We demonstrate the step-by-step process and...

👉Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes the each of the equation in the system true. To solve a system of equations by...

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which...

👉To solve a system of equations means to obtain a common x-value and a common y-value that makes the each of the equation in the system true. To solve a system of equations by graphing means to obtain the point of intersection (if any)...

👉 Learn how to evaluate the integral of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiation. Integral of a function can be evaluated as indefinite integral or as a definite...

The video is a lecture on non-colinear resultant forces and how multiple forces acting on an object at angles to one another can affect it. The speaker initially explains collinear forces and how to find the resultant force. They then...

👉 Learn how to solve for an unknown variable using parallel lines and a transversal theorems. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry,...

The video is a lecture presentation on solving quadratic inequalities. The speaker begins by reviewing inequality symbols and explains how they provide a range of values rather than a single answer. The speaker then explains the process...
