In a Year 5 maths lesson, students revisit the fundamental concepts of triangles, focusing on the three main types and their distinct features. The first type of triangle discussed is the equilateral triangle, notable for its three sides of equal length and three equal angles. To visually indicate the sides are the same, small markings are drawn on each side. In an equilateral triangle, all angles are equal to 60 degrees, as shown in the provided diagram where angles a, b, and c are each marked as 60°.

The lesson then moves on to the right-angled triangle, which is characterized by having one angle that measures exactly 90 degrees, known as a right angle. This is represented in the diagram by angle n. Lastly, the isosceles triangle is introduced, with its defining property of having two sides of equal length and two equal angles. In the example given, sides RP and RQ are of the same length, and angles p and q are equal. These descriptions and visual representations help students to identify and differentiate between equilateral, right-angled, and isosceles triangles, reinforcing their understanding of triangle classification.
