In this video, the teacher explains how to prove the Pythagoras theorem using the concept of similar triangles. They break down the steps in a clear and concise manner, making it easy for students to understand and follow along.

Parallel lines are always the same distance apart and never meet.



We use arrowheads are used to show that lines are
parallel.
See how these lines have one arrow the, because these ones are also...

The video is a math test prep where the teacher guides the students on how to identify the surface area of a right triangular prism gift box using a net. The teacher encourages the use of mathematical reference sheets and formulae to...

This video explains the basic concepts of triangles, including the relationship between angles and sides, the properties of equilateral, isosceles, and scalene triangles, and the special case of right-angled triangles.

👉 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 Episode, Tyler Teaches Us About Congruent Shapes

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?

In this video, students learn how to find the sine value of an acute angle in a right triangle. It explains the properties of right triangles, such as the relationship between the hypotenuse and the legs, as well as the concept of...

This video...

The three dimensions that form a solid are: length, width, and height.

Identifying special types of triangles based on the angle properties such as right triangles, obtuse triangles, and acute triangles.

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,...

👉 Learn how to find the corresponding pairs of congruent triangles. Two or more triangles are said to be congruent if they have the same shape and size. To determine the corresponding congruent parts of a triangle, we use the congruent...

Learn about the characteristics of right, acute, and obtuse triangles. This video demonstrates how to determine if a triangle is right using the theorem and highlights common mistakes students make.

In this video we are going to look at square, cube and triangular numbers, what they are, how they can be useful and some of the patterns they form

How to calculate surface area.

👉 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...

Write the equation of a circle given the center and point

👉 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...
