Today we learned more about similar shapes. We reviewed the rules for telling weather two polygons are similar, which were equal angles, proportional sides, and the same basic shape. Finally, we learned how to find the angle measures and side lengths of 
one triangle, using it's similar shape. The picture to the left shows two similar triangles, UVY and XYZ. As you can see, all three of the corresponding angles are marked with the same number of arcs, which means that they are equal to eachother. The sides are also proplotinal to eachother. The scale factor of XYZ to UVW is two. This means that the are of XYZ is four times as large as the area of UVW. Finally, you can tell that they are similar because of their basic shape. This is one important rule used to find out if two shapes are similar.
