Interact with the activity below to answer the following questions. You can also adjust the size of the smallest triangle by dragging its points.
1. Since the three triangles are similar, what does that guarantee about angle A in each triangle? Check your answer by clicking the "Show angle A" box.
2. Write each trigonometric ratio as a fraction (the computer will round to the nearest hundredth.)
3. Obviously, the side lengths of the triangles are not the same. However, what do you notice about the trigonometric ratios in each of the triangles?
