Give two different examples of pair of (i) similar figures. (ii) non-similar figures.
Give two different examples of pair of similar figures.
Two circles are similar figures. The context states that all circles have the same shape, so they are all similar. Another example is two squares. All squares are similar because they have the same shape, though they may not be congruent if sizes differ.
Give two different examples of pair of non-similar figures.
A circle and a square are non-similar figures. The context indicates these figures do not have the same shape. Another example is a square and a rectangle. The context notes that while their corresponding angles are equal, their corresponding sides are not in the same ratio, making them non-similar.
Explanation
The textbook context explicitly lists all circles and all squares as examples of similar figures because they maintain the same shape regardless of size. For non-similar figures, the context distinguishes between shapes with different geometries (like a circle and a square) and shapes that look similar but fail the mathematical criteria, such as a square and a rectangle where the side ratios differ.
