The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

The Pythagorean Theorem, a cornerstone of geometry, empowers students to solve right triangle problems and unlock advanced ...

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles ... deck and rigging rope form a right triangle. If we know how far the rope is ...

With this curve I find out everything I need to know about that right triangle with just an angle and the length of the hypotenuse. Knowledge is power (as you will see). But where is the trig?

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.

Pythagoras is a star of trigonometry for his alleged discovery of the Pythagorean theorem, which states that "in a right-angled triangle the square of the hypotenuse is equal [to the sum of] the ...

The mathematical study of triangles has just got ... engineering and construction today. Classical trigonometry calls the separation between two lines an "angle", which is the length of a circular ...
