👉 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...

👉 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 evaluate trigonometric functions using the special right triangles. A right triangle is a triangle with 90 degrees as one of its angles. A special right triangle is a right triangle with the angles 30, 60, 90 degrees or...

👉 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 answering the question of are there different types of triangles.

In this lesson I will show you how evaluate the six trigonometric functions with right triangles. We will begin by finding the missing side of a triangle with the pythagorean theorem and then transcend into identifying the sides of a...

In this video lesson, we will learn the definition of similar figures. Similar figures are figures that are the same shape but different sizes. Similar figures have corresponding sides that are proportional and corresponding angles...

Classifying triangles based on the sides’ length.

CCSS What are equiangular, equilateral and regular polygons

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 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.

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...

In this video, the teacher explains how to determine the number of lines of symmetry in regular polygons. They discuss the three options for line symmetry: horizontal, vertical, and diagonal. Using examples of an equilateral triangle,...

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?

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)...

Identify lines of symmetry in regular polygons.

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. ...

In this online video we will learn Types of Triangles based on angles and sides.

👉 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...

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.

If a shape is made of straight line segments, the minimum number of sides it can have is three. And three sides make a triangle! I'm sure you knew that. But do you know all the types of triangles? Oh you do? Then what's a scalene...
