Do you think there’s a triangle whose angles measure 41, 76 and 63 degrees? At first, answering this may seem easy. From geometry class we know that the sum of the measures of the interior angles of a ...

In this triangle \(a^2 = b^2 + c^2\) and angle \(A\) is a right angle. Pythagoras' theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.

The textbook uses examples from Indian monuments and cultural contexts to explain key concepts of the subject, including ...

The most important theorem we learnt in childhood carries the name of a Greek philosopher, but not necessarily the legacy. Evidence increasingly shows that the theorem existed long before his lifetime ...

Two years ago, a couple of high school classmates each composed a mathematical marvel, a trigonometric proof of the Pythagorean theorem. Now, they’re unveiling 10 more. For over 2,000 years, such ...

The Pythagoras theorem 'should either be an Egyptian theorem if you look at the standard of just having an idea about it, an Indian theorem if you're looking for a complete statement of it, or a ...

The longest side of a right-angled triangle is the hypotenuse. The hypotenuse is always opposite the right angle. Draw a square on each side of a right-angled triangle. Calculate the area of each ...
