In this maths lesson, students will explore how the sine rule allows possible triangles to be solved, given combinations of two angles and a side or two sides and an angle that is not in between. They ...

In this maths lesson, students are given 15 angles and 15 lengths and have to work out how they can be placed into 5 right-angled triangles. Finding triples of angles that sum to 180° is fairly easy, ...

Similar triangles are an important concept in geometry. They are defined as triangles that have lengths of their sides in proportional ratios. Teaching students to identify similar triangles can be ...

The humble triangle has been with us from the ancient pyramids to the modern days, being one of the most recognizable, interesting, and useful shapes in geometry. Ancient mathematicians laid the ...
