Comparing ratios is really important when we want to find out if two geometric shapes are similar. Here’s how we can do it:
Side Length Ratios: If the ratios of the side lengths for two shapes are the same, then those shapes are similar. For instance, if two triangles have side lengths in the ratio of 3 to 5, they are considered similar.
Angle Measures: For two shapes to be similar, the angles that match up must be equal, or the same size.
Scale Factor: The scale factor comes from the side length ratios. It helps us understand how much one shape has been made larger or smaller compared to the other shape.
In summary, comparing these ratios is really key to showing that two geometric shapes are similar.
