Essential Question: How do i use ratios and porportions to solve Geometric problems?

Ratios and Porportions are really closely related to shapes and angles, in other words Geometry.When creating porportions, the shapes in Geometry help you to create them. For example, lets pretend you have 2 triangles and you are trying to find the values of the unknown values in the triangle. you get the sides that are similar and you turn it into a porportions, and whatever you get that is the answer for the value of the unknown value. Ratios are a big help when you are doing scale factor, you need ratios and porportions to do those. For example, when you havre a blue print of something you would set up the porportion as  the actual length over the model
