In this video, students learn how to efficiently find the ratios of side lengths for similar triangles, even when their sizes are different. They will understand the concept of similarity in triangles and how corresponding angles have an...

In this video, the teacher explains how to determine if two triangles are similar by using similarity transformations. They review the different types of transformations that preserve shape and size, such as translation, reflection,...

In this video, we review the sum of the interior angles of a triangle and explore the relationships between interior and exterior angles. The teacher provides visual proofs for the theorems and demonstrates how to use them to find...

👉 Learn how to evaluate the six trigonometric functions given a right triangle. A right triangle is a triangle with 90 degrees as one of its angles. A right triangle is made up of two legs, which formed the sides of the 90 degrees angle...

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...

This video explains the concept of similar triangles and their side and angle relationships. The video discusses how similar triangles have the same shape but not necessarily the same size, and how dilations and translations can be used...

👉 Learn the essential definitions of triangles. A triangle is a polygon with three sides. Triangles are classified on the basis of their angles or on the basis of their side lengths. The classification of triangles on the bases of their...

In this video we are going to look at the angles in polygons… the sum of all interior angles and the size of one interior angle. In another video we will look at exterior angles.



Before we start, you should...

This video talks about Ratios of The Areas of two Similar Triangles through an activity

In this video lecture, the presenter explains the concept of area and how it is calculated by multiplying two side lengths together. The focus of the lecture is on the area of triangles and how it is closely linked to the area of a...

What is the area of a rectangle? How would you calculate the area of a triangle using a rectangle? What is the area of a triangle?<br/>
Area Of Triangles, Part 1

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...

Covers the tricks to understand circle theorems & know what each theorem states. Also covers the basics knowledge required before solving a Circles theorem.

The video teaches how to make an origami cube using a unique approach. The tutorial provides step-by-step instructions using a square sheet of paper and demonstrates how to attach the six sides together to create the cube.
