Pupil outcome: I can apply knowledge of Pythagoras' theorem to 3D problems. Key learning points: - For packing efficiency, it can be useful to know the length of the longest diagonal - This would be from a bottom corner of a rectangular...

In this video, we do two quadratics word problems. The first involves two square and their areas. The second involves a right triangle with polynomial side lengths.

This video discusses how to find geometric probability using the formula (area of a success)/(total area). We begin by defining the geometric probability, then we look at several examples, including an example with a number line. These...

In this video, we investigate how to find trig ratios when given other ratios. First, we define all six trig ratios, then we examine for which quadrant each angle is positive and negative. Then, we work two examples.

In this video, we are going to derive the Pythagorean Identities (proofs) and then we will simplify expressions using these identities. We will work through 3 practice problems.

How to solve problems with bearing using trigonometry. Bearing is often used as a way of describing direction in sailing and navigation. Once you know the basic definitions and some trigonometry, you can use bearing to find direction and...

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

How do you write the linear combination of unit vectors? How do you write the unit vector in the same direction as a given vector? What are the standard unit vectors? This video answers all of these questions and tells you all the basics...

How do you find magnitude and direction of a vector? How do you write a vector in component form? This video will discuss how to find all of the above. We define vector, component form, magnitude, direction, standard position, and...

What is the polar coordinate plane and how do we convert points between rectangular and polar form? We start this video by graphing polar points, then we learn how to convert between polar and rectangular/Euclidean form.

We all know the Pythagorean Theorem, but what can we conclude if a^2 + b^2 is NOT equal to c^2?

In this math video we will determine the proof of the Pythagorean Theorem using squares. We will be present with an image created from three squares connected at their vertices to form a right triangle in the center. We will be presented...

In this math video we will solve a math problem using the converse of the Pythagorean Theorem. We will understand the if the longest side of a triangle squared is equal to the sum of each square of the remaining two sides, then the...

In this math video we will find distance in the coordinate plane. We will understand that we can create a right triangle using a coordinate plane. We will also understand that the Pythagorean Theorem applies to any right triangle and is...

In this math video we will be using the Pythagorean Theorem to solve a real world problem. We will understand that the Pythagorean Theorem applies to any right triangle. We will identify the legs and hypotenuse of a right triangle. We...

In this math video we will determine the possible lengths of the missing side of a right triangle. We will be given two side lengths and asked to determine two possible lengths for the third side. We will understand that the Pythagorean...

Pythagoras' Theorem Explanation: This video is an introduction lesson for Pythagoras' Theorem. Why is it useful to know Pythagoras' Theorem? What is a hypotenuse? Watch this video to find out. Practice questions and answers are at the...
