In right-angled triangles the square on the side subtending ... allowing us to calculate distances in terms of coordinates. It also inspired trigonometry." What else did it inspire?

But do you really understand the very basic concepts of trig? Yes, I just call it "trig" because I always misspell trigonometry. Maybe you can use ... the small triangle. So, if you find this ...

Save guides, add subjects and pick up where you left off with your BBC account. The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles.

Draw the right-angled triangle OVC and label the sides. The angle between VC and the plane is \(y\). It is not possible to use trigonometry to calculate the angle \(y\) because the length of ...

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry ... triangle's two shorter sides are equal to the square ...

Our new research, published in Historia Mathematica, shows that the Babylonians were able to construct a trigonometric table using only the exact ratios of sides of a right-angled triangle.
