In this video I show you how to set up an equation and picture from a word problem. Most of the time students have trouble with word problems because they do not know what to look for or how to solve. So I work through 28 different...

👉 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 solve for the unknown in a triangle divided internally such that the division is parallel to one of the sides of the triangle. The triangle proportionality theorem states that if a line is parallel to one side of a...

Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing...

In this video we will discover how to find the missing side of a right angle triangle using SOHCAHTOA.



You should already know which side is the opposite, adjacent and hypotenuse. Sin, cos and tan are ratios between...

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

In this video I will show you what you should expect to know before starting your chapter on Applications of Trigonometry. In applications of trigonometry we will explore solving trigonomtric word problems, law of sines, cosines,...

👉 Learn how to solve for the unknown in a triangle divided internally such that the division is parallel to one of the sides of the triangle. The triangle proportionality theorem states that if a line is parallel to one side of a...

👉 Learn how to evaluate inverse trigonometric functions. When an angle is unknown but the value of one of the trigonometric functions of the angle is known, we can evaluate the value of the angle using the inverse trigonometric function...

Trigonometry | Preparing for Precalculus Part 6

This video teaches the basics of trigonometry and how to use it to find missing lengths and angles in a triangle. The presenter explains the three trig functions (sine, cosine, and tangent) and offers memory aids to remember them. The...

During this video lesson, students will be introduced to the Pythagorean Theorem which is read a squared plus b squared equals c squared. Students will learn key vocabulary and how to identify the legs and hypotenuse of a right...

In this video we will explore how to handle the ambiguous case with two triangles. We will do this by finding the acute and obtuse triangle. Timestamp 0:00 Intro 1:00 Case #1 First Triangle (Acute) 4:46 Case #1 Second Triangle (Obtuse)

This video teaches the Pythagorean theorem, explaining its proof and how to use it to find missing side lengths of a right triangle. The lesson includes key vocabulary and examples with step-by-step instructions, making it easy to...

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 sides...
