WebSo as in the figure on the right, the triangle ABC has angle A = 60º and angle B = 30º, which forces the angle C to be 90º. Thus, ABC is a right triangle. We see that the hypotenuse … WebAn angle smaller than a right angle (less than 90°) is called an acute angle ("acute" meaning "sharp"). An angle equal to 1 / 4 turn (90° or π / 2 radians) is called a right angle. Two lines that form a right angle are said to be normal, orthogonal, or perpendicular.

WebObserve the triangle ABC given below in which angle A = 90º, and we can see that AB = AC. Since two sides are equal, the triangle is also an isosceles triangle. We know that the sum of the angles of a triangle is 180º. Hence, the base angles add up to 90º which implies that they are 45º each.
