Steps Into Trigonometry Mind Map
Trigonometric Identities
These resources are about trigonometry which is the study of triangles. They can help you understand the terminology and definitions used in the subject.
These resources are about Pythagoras' Theorem which is a famous piece of mathematics. It is useful when you are solving right-angled triangles as you can use it to calculate the length of one side if you know the lengths of the other two.
These resource are about the trigonometric identities (sine, cosine and tangent). They are properties of the angles in right-angled triangles.
