It is literally saying that because the angle is perfect,the angle isn't wrong, it is a right angle, it is considered right or true. The word "right" is used for this angle because the word has the meaning of "true" or "correct." When a carpenter is building a house and he positions a wall, he wants that wall to be correctly placed; to be "right" or "true."
The presence of a right angle in a triangle is the defining factor for right triangles, making the right angles basic to trigonometry. The term is a calque of Latin angulus rectus; here rectus means "upright", referring to the vertical perpendicular to a horizontal base line.
