proportions are equal things like say 10 hot dogs = 10 hamburgers. same for simalar figures except with shapes or figures.
proportions are used in scale factors; scale factors ARE proportions
Any two corresponding sides in two similar figures have a common ratio called the scale factor. Since the figures are similar, the ratios of the lengths of corresponding sides of the figures are equal. 1. Match a side of both figures, 2. write the proportions 3. substitute the values 4. Write the cross product 5. Divide both sides by a common factor 6. simplify 7. Convert improper fraction into mixed number
All congruent figures are similar figures, and have identical sizes.
The concept of proportion has its roots in ancient mathematics, particularly in the work of the Greeks around the 5th century BCE. Mathematicians like Pythagoras and later Euclid explored the relationships between numbers and geometric figures, laying the groundwork for understanding proportions. The formal study of proportions was further developed in the context of ratios and similar figures during the Renaissance.

Congruent figures are always similar. However, similar figures are only sometimes congruent.

Similar figures are geometrical figures, which have the same shape but not the same size
No not all rectangles are similar because the proportions are different.
Yes, two objects of the same height but with different proportions are considered to be similar in size.
No, not all rectangles are similar because the proportions are different.
Are congruent figures always similar? Yes.
