1. These triangles are similar as they all have the same angle of 30°.
2. The sides in red are known as the opposite, and the sides in purple are the hypotenuse, and they can be used to find missing angle or side.
3. Triangle 1: red side: purple side
4.8:9.6 you can divide both side by 4.8 so the new ratio will be.
1:2.
Triangle 2: Red side: purple side
7.2:14.4 You can divide both sides by 7.2 So the new ratio will be
1:2.
Triangle 3: Red side:purple side
5.4:10.8 You can divide both sides by 5.4 to give.
1:2.
4. All three triangles have the same ratio of red side to purple side. This was as expected as all three triangles are similar and have an equal corresponding angle of 30°.
I hope this makes sense to you and helps you out! :)
