...perpendicular to another, the angle between them is a right angle, and the triangle is a right-angled triangle. The side opposite the right angle is called the hypotenuse; the other two sides, the base and perpendicular. Thus, ABC is a right-angled triangle; AB being the base, BC the perpendicular,... | |

...one of the angles is formed by two lines perpendicular to each other, the triangle is a RIGHTANGLED TRIANGLE. The side opposite the right angle is called the hypotenuse; the other two sides the base and perpendicular. Thus, ABC is a right-angled triangle ; AB is the base, AC the perpendicular,... | |
