Scale Factors and Their Properties

The video tutorial covers the concept of scale factors using geometric shapes like rectangles, triangles, and quadrilaterals. It explains how to determine if a shape is a scaled copy of another by comparing their scale factors. The tutorial also discusses the reciprocal relationship of scale factors and simplifies ratios to identify equivalent ones.

What are the names of the rectangles discussed in the practice problems?

• X, Y, Z, W

• P, Q, R, S

• L, M, N, O

• A, B, C, D

If a scale factor is greater than one, what does it indicate about the shape?

• The shape is larger

• The shape is smaller

• The shape is unchanged

• The shape is distorted
