Tip Pro

To check if a triangle is a right triangle: compute a²+b² and c². If equal, it's a right triangle. Also: if a triangle's longest side satisfies c²>a²+b², it's obtuse; if c²<a²+b², it's acute.

Kesulitan:Menengah

Tahukah Anda?

The 3-4-5 right triangle was known to ancient Egyptians, who used knotted ropes with 12 equal spaces to create right angles for surveying land after Nile floods. This "rope-stretching" method is one of the earliest practical applications of the Pythagorean theorem.
