In this video, the teacher explains how to use the properties of parallelograms and triangles to solve real-world problems. They demonstrate this by using the example of constructing a wooden gate, where they determine the lengths of...

👉 Learn how to find the missing side of a triangle. A triangle is a polygon with three sides. Triangles are classified on the basis of the angles or on the basis of the sides. The classification of a triangle on the basis of the sides...

This is an educational video that explains various circle theorems, which are important geometrical concepts related to angles and chords in a circle. The presenter goes through each theorem and provides examples and visual aids to help...

The video is a lecture presentation on triangles, discussing the different types of triangles and their properties. The presenter explains the meaning of the word "triangle," which refers to a shape with three sides, and goes on to...

In this video, the teacher explains how to draw geometric shapes using only the lengths of their sides. They demonstrate how to draw triangles with different side lengths and explore the concept of congruent triangles. They also show how...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

In this video we are going to look at exterior angles of polygons. Exterior angles are a little strange. They make a straight line with the interior angle, rather than being the whole outside angle. There are a few different ways to...

This video explains the properties of an isosceles triangle and helps viewers answer a standardized math test question about it. The teacher breaks down each answer choice and shows how to arrive at the correct answer.

👉 Learn how to find the missing side of a triangle. A triangle is a polygon with three sides. Triangles are classified on the basis of the angles or on the basis of the sides. The classification of a triangle on the basis of the sides...

This video is an educational tutorial on triangles. The instructor begins by explaining how to classify triangles based on their angles, including acute, obtuse, and right angle triangles. Next, the video covers the three special types...

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.

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?

Teaching Award winner Jonny Heeley inspires a group of gifted and talented KS2 pupils with an active lesson about polygons. With an emphasis on pupil participation, Jonny explores the definition of a polygon before helping them produce...

In this video we will learn about Inequalities of a Triangle. We will cover Introduction, 3 theorems and solve some questions.

👉 Learn about congruent triangles theorems. Two or more triangles are said to be congruent if they have the same shape and size. There are many methods to determine whether two triangles are congruent. Some of the methods include: (1)...

This video is a lecture presentation on quadrilaterals. The speaker explains what a quadrilateral is and goes through several different types, including a square, rectangle, trapezium, isosceles trapezium, rhombus, parallelogram, and...

Skateboards, mountain climbing, billiards' Don't you just love this stuff? That's why NUMBEROCK put it all into this song about triangles that is filled with real-world connections. Triangles are all around us, so it is easy to make this...

It explains linear pair axiom and theorem on intersecting lines. It also provides problems based on the axiom and theorem.

In this video, students learn how to draw triangles when given the angles. The teacher explains the concept of the sum of angles in a triangle always being 180 degrees and demonstrates how to use a protractor to draw the angles accurately.

In this series of programs students are introduced to perimeter and area. Easy-to-understand examples enable students to understand the process by which perimeter is calculated. The area of rectangles, parallelograms, and triangles is...

Understand and making sense of geometry: Proofs continued. This is part 3 from the series 'Geometry Program'.
