Two high school students have proved the Pythagorean theorem in a way that one early 20th-century mathematician thought was impossible: using trigonometry. Calcea Johnson and Ne’Kiya Jackson ...

A high school teacher didn't expect a solution when she set a 2,000-year-old Pythagorean Theorem problem in front of her students. Then Calcea Johnson and Ne'Kiya Jackson stepped up to the challenge.

Trigonometry explores the relationship between sides and angles in right-angled triangles.. The sides of a right-angled triangle are labelled with: Hypotenuse (\(h\)) – the longest side, which ...

Luckily, triangles survived nonetheless—and thrived. In “Love Triangle: How Trigonometry Shapes the World,” Matt Parker recounts, for instance, how computers were a “game-changer in the ...
