Similar Shapes
This lesson covers the identification of similar shapes such as triangles, rectangles, squares, cubes, and cuboids. It explains the criteria for similarity, including proportional sides and equal angles. The lesson also includes methods for enlarging figures using scale factors and calculating lengt
- 00:00 “Hello, my name is Sonday Ayase. We're taking Mathematics, JSS, three class, we're looking at a very interesting topic today. The say is similar shapes. Can shape actually be similar? Yes. They can. One can be bigger, one...”

Plane Figures and Their Properties
This lesson covers the identification and properties of various plane figures such as squares, rectangles, triangles, and circles. It explains how to calculate the area and perimeter of these shapes. The lesson also includes the classification of triangles their sides.
- 04:43 “A socialist triangle is a triangle with two equal sides and equal base angles. Two sides of an isosceles triangle are equal. The third side is not of the same angle or the same length as the remaining two sides. Two side...”
- 02:47 “Identifying plane shapes. Properties of a rectangle. The opposite sides are equal and parallel. It has equal angles. Each angle at 90 degrees. For a rectangle, each angle is at 90 degrees. This is 90 degrees, 90, 90, and...”
- 01:53 “Different plane shapes have different attributes, such as the number of sides and corners. A side is a straight line that makes part of the shape, and the corner is where two sides meet. For example, let me give an illus...”
