Question

three - dimensional drawing in which all the sides are measured full size and scaled with the drawing at 30° to the horizontal is known as ______________.
a. two point perspective \tc. linear perspective
b. isometric perspective \td. multiple point perspective
please select the best answer from the choices provided
○ a
○ b
○ c
○ d

Explanation:

To solve this, we analyze each option:

• Option a (two - point perspective): It uses two vanishing points and doesn't have sides at a fixed \(30^{\circ}\) to the horizontal with full - size measurement.
• Option b (isometric perspective): In isometric drawing, all sides are measured at full size, and the axes are typically at \(30^{\circ}\) to the horizontal. This matches the description in the question.
• Option c (linear perspective): It's a broader term for perspective drawing that creates the illusion of depth, and it doesn't have the specific characteristic of sides being at \(30^{\circ}\) to the horizontal with full - size scaling.
• Option d (multiple - point perspective): It uses more than two vanishing points and doesn't fit the given description.

Answer:

B. isometric perspective
