Answer:

A right triangle is a triangle in which one of the angles is a 90∘ angle.

Step-by-step explanation:

The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.
