SchoolOnline's Primary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 9-13, they cover every key topic and sub topic covered in Maths in clear and easy to follow steps. This video looks at...

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...

Which shape is which by pointing to it. Drawing and saying colors. Shapes & Colors, Part 3

👉 Learn all about the trigonometry of right triangles. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles give us the relationship between the angles of a right...

Identifying the properties of polygons and special types of polygons like quadrilaterals and triangles.

In this video we will learn how to draw Landscape/Scenery with Geometric Shapes

4a Example 2

Master composing inverse trig functions

👉 Learn how to solve the word problems with trigonometry. Word problems involving angles, including but not limited to: bearings, angle of elevations and depressions, triangles problems etc are solved using trigonometry. To be able to...

It explains the criteria of congruence such as SSS, SAS and ASA. It also states the conditions for proving two right-angled triangles to be congruent.

👉 Learn about congruent triangles theorems. Two or more triangles (or polygons) 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...

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...
