Which statement is true about an architect's triangular scale?

It has 8 scales It has 10 scales It has 6 scales It has 12 scales

Correct Answer:

It has 12 scales

Explanation:

An architect’s triangular scale is a drafting tool designed to read multiple proportioned measurements from drawings. It’s formed as a triangle with three faces, and each face carries several scales. Because there are four scales on each face and three faces, there are twelve scales in total. This arrangement lets you switch quickly between common drawing proportions (such as different inch-to-foot scales) on a single ruler. So the true statement is that it has twelve scales.
