Rotating a triangle 90 degrees counter clockwise

Показать описание

👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also important to understand the direction that you will have to rotate. We will rotate either in the clockwise or counterclockwise direction. While we can rotate any degree in this playlist we will only focus on rotating a figure 90,180,270 and 360 degrees.

If the point is already negative do you keep it or change it to a positive number.

What if the Y coordinate is already a negative? Do I change it to a positive number after i bring it over?

Thank you! Enormously helpful to my 8th grader!

this might sound dumb but in my head it sounds reasonable. when you change from (x, y) to (-y, x) why was the -y on the x axis? Does that question make any sense at all?
