What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but may differ in size, meaning their corresponding angles are equal and their corresponding sides are proportional.

What is the relationship between scale and real-world measurements?

Back

The relationship between scale and real-world measurements is defined by the scale factor, which indicates how much the drawing or model is reduced or enlarged compared to the actual size.

What is the formula to find a missing side in similar figures?

Back

The formula to find a missing side in similar figures is: (side length of figure A) / (side length of figure B) = (missing side length of figure A) / (corresponding side length of figure B).
