👉 Learn how to solve with similar polygons. Two polygons are said to be similar if the corresponding angles are congruent (equal). When two polygons are similar the corresponding sides are proportional. Knowledge of the length of the...

👉 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,...

👉 Learn how to find the distance between two points. The distance between two points is the length of the line joining the two points in the coordinate plane. To find the distance between two points in the coordinate plane, we make use...

👉 Learn how to find the area and perimeter of trapezoids. A trapezoid is a quadrilateral with one pair of parallel sides. The area of a shape is the measure of the portion enclosed by the shape while the perimeter of a shape is the...

Learn how to solve problems with tangent line. A tangent line to a circle is a line that touches the circle at exactly one point. The tangent line to a circle makes a right angle with the radius of the circle at the point of its...

Postulates of Quantum Mechanics: Hermitian Operators 2

Learn about compound interest. We will look at how to determine the final value, initial value, interest rate and years needed. We will investigate problems compounded continuously, daily, weekly, monthly, quarterly and yearly. These...

👉 Learn how to find the domain of rational functions with a radical numerator. Recall that the domain of a function is the set of possible input values (x-values) of the function. For a rational function, the denominator cannot be zero...

👉 Learn how to verify Pythagoras trigonometric identities. A Pythagoras trigonometric identity is a trigonometric identity of the form sin^2 (x) + cos^2 (x) or any of its derivations. To verify trigonometric expression means to verify...

Ethical troubles can show up when you least expect it causing you to have to make some tough decisions. While they may be different scenarios, the anatomy of the decision-making process is often the same. In this course we will learn the...

In this video, the teacher explains how two different equations can have the same solution by applying properties of equality and real numbers. They provide examples and demonstrate how performing the same operation on both sides of an...

It's only a matter of weeks since the UK officially left the EU, and many of the consequences for the Island of Ireland and the Irish Border still haven't come into force. However, that still hasn't stopped an escalating conflict between...

The fire that swept through the NSW town of Cobargo destroyed homes and businesses and killed two people, but the death toll could have been higher.

Matt and Justine Schofield are making the perfect dessert for impressing a date. Creme caramel. It’s simple to make but looks and tastes lovely.

How to write the equation of a circle in polar form to rectangular

👉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 how to graph a system of inequalities. A system of inequalities is a set of inequalities which are collectively satisfied by a certain range of values for the variables. To graph a system of inequalities, each inequality making...

In this video we will learn types of paper required for origami.

👉 Learn all about the processes and definitions for solving linear equations. You will gain a better understanding about the vocabulary and steps used to solve liner equations such as how to isolate an equation and apply inverse...

👉 Learn how to solve for an unknown variable in the interior angle of a polygon. A polygon is a plane shape bounded by a finite chain of straight lines. The interior angle of a polygon is the angle between two sides of the polygon. The...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

👉 Learn how to find a missing side length of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles give us the relationship between the angles of a...
