Ratios, Triangle similarity, and dilations in real life.

Retinal Scans

Retina scans I chose this one because I found it fascinating when they get the pictures of your eye at the optometrist. This represents dilation in 2 ways: The pupil dilating so that the retina can be seen and also the dilation of the image so that it can be examined properly.

"​After assessing your visual acuity, your optometrist will put a series of drops into your eyes. These drops will stimulate your pupils, making them expand or dilate. Because the drops do not allow the pupils to constrict (get smaller), they provide larger “windows” for your doctor to view the back of your eyes." - https://www.allaboutvision.com/eye-exam/dilated-eye-exam/

Cameras

I Chose this example of similar triangles because I took photography in 6th and 7th grade and had osme experience with the subject. This works as an example of similar triangles because the triangles of light recieved and that projected to the weiwing glass need to be similar or the image will appear stretched or compressed.

"In the above setup for a camera lens, we have a “Bow Tie” shaped pair of Similar Triangles." - https://passyworldofmathematics.com/similar-triangles-applications/

The kdr

I chose this example because I like to play video games. The kdr is how many people youve killed in game compared to how many times youve died. This is an example of ratios in real life because is it a ratio used for measurement of skill.
