One way that we applied transformations to the real world was through discussing how video games were made when they were designed by hand in the early 1980s. We went through the process of designing our own video games which consisted of translations, rotations, and reflections that helped navigate the players of the video game. https://youtu.be/RQ0RSRrJHkI

It was important throughout this process that we remember the differences between translations, reflections, rotations, and dilations. Translations are a slide, they are up and down movement on the y axis and sideways movement on the x axis. Reflections are a flip across an axis or a line. Rotations turn a certain amount of degrees and dilations are a size change of the shape, multiplication for an increase and division for a decrease.

These transformations can apply to the real world in a number of ways that I personally have seen, such as dance movement. Silly yes but applying strategies like this can put more pep in your step, knowing when to slide (translation) and when to pop and spin (rotation).

One way that right triangle trigonometry applies to the real world is through finding the length of distances between 2 points. In geometry we used google maps and created right triangles from different neighborhoods in Atlanta. We used trig. Ratios to determine the length of the distance between the neighborhoods to different resources such as the hospital and grocery store. We then compared the length of these distances to the income in the neighborhoods. This helped to show the inequalities present in many areas in Atlanta.

We have applied right triangle trigonometry a lot recently in my physics class, which is basically another math class. We use the same concepts like soh-cah-toa and use this math to figure out lengths of sides and angle measurements for IRL problems.
