Final answer:
Linear perspective is a technique used by artists to create the illusion of depth on a two-dimensional surface. It involves using parallel lines that converge at a vanishing point.
Step-by-step explanation:
Linear perspective is a technique used by artists to create the illusion of three-dimensional space on a two-dimensional surface, such as a painting or a piece of paper. It is based on the optical illusion that parallel lines appear to converge as they recede into the distance. Artists use orthogonal lines that converge at a vanishing point on the horizon line to create this effect. Artists during the Renaissance, such as Filippo Brunelleschi and Michelangelo, were pioneers in using linear perspective to give their artworks a sense of depth and realism.
