👉 Learn how to factor polynomials by GCF. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. To factor an algebraic expression means to break it...

This video discusses different methods for solving right triangles and oblique triangles, and provide examples of applying these methods to find side lengths, angles, and distances in various scenarios. The lesson emphasizes the...

In this video, the teacher explains how to simplify radical expressions without using an area model. Learn how to factor to break down the radicals into their prime factors, and then simplify the expression by finding pairs or triples of...

👉 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...

In this video, the teacher explains how to find the missing side length of a rectangle by dividing its area. Students learn to multiply and divide to calculate the width of the stripes or curtains based on the given area and known side...

Working with triangles.

In this lesson, students will learn how to solve equations involving cubes and cube roots. They will understand the concept of cubing a number, finding the cube root, and the relationship between squaring and square rooting.

I think we all learn how to classify triangles, but why do we learn it and how is it helpful for us to solve math problems?

👉 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...

The video explains the different criteria or conditions that can be used to prove that two triangles are congruent or identical to each other. The speaker discusses four different rules: side side side, two sides and the included angle,...

Master Finding the Area and Perimeter of a rectangle given four points

In this video, the teacher explains how to find the scale factor or constant of proportionality in an architect's scale. The concept of ratios, proportions, and scale factors is introduced, and division is used to determine the scale...

Pyramid of Circles | Can you Solve?

In this video we will cover the key topics you will need to know before starting our chapter on Trigonometry in Pre-calculus. We will start by working through the Pythagorean Theorem and then working through the trigonometric identities...

In this video, we review the concept of similarity, where corresponding angles are congruent and corresponding sides are proportional. This lesson helps students understand the criteria for similarity and how it applies specifically to...

The video is a lecture presentation on the four different congruency criteria for triangles. The presenter explains that congruent shapes are exact replicas of the originals with the angles and side lengths preserved. However, in some...

👉 Learn how to determine if a given SSA triangle has 1, 2 or no possible triangles. Given two adjacent side lengths and an angle opposite one of them (SSA or ASS), then there are 3 possible cases: there can be 1 solution, 2 solutions and...

Explore the concept of volume and understand the formula we use to calculate it, which involves cubing the side length of the cube. Through examples and step-by-step explanations, students will gain a clear understanding of how to apply...

How to calculate area.

This video is a lecture on Pythagoras's theorem, a fundamental concept in geometry that describes the relationship between the sides of a right-angled triangle. The video explains who Pythagoras was, his contribution to mathematics, and...

In this video lesson you will learn about congruent figures. We will learn the definition of congruent figures. Students will learn how to identify corresponding sides and corresponding angles to determine if figures are congruent. ...

👉 Learn about the points on the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle...

👉 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...

All is quiet inside the anthropology and archaeology museum… until Carmen strikes again! This lesson will apply Newton’s 2nd Law of Motion to moving and accelerating objects.

Definitions included: Newton’s 2nd Law of Motion,...
