Question

problem 7 here is an equilateral triangle. here is the scaled copy you drew on the previous screen. equilateral triangles are always scaled copies. what other shapes are always scaled copies?

Explanation:

Similar - shaped figures with all corresponding angles equal and side - lengths in proportion are scaled copies. Regular polygons (like regular hexagons, squares) and circles have consistent shape characteristics. For regular polygons, all angles are equal and side - length ratios are constant between similar ones. Circles are defined by a single parameter (radius), and any two circles are similar.

Answer:

Regular polygons (such as squares, regular hexagons) and circles.
