How many degrees inside a triangle
WebIf you have a point on (2, 1) and rotate it by 90 degrees, it will end up at (-1, 2) When you rotate by 90 degrees, you take your original X and Y, swap them, and make Y negative. So from 0 degrees you take (x, y), swap them, and make y negative (-y, x) and then you have made a 90 degree rotation. WebJan 31, 2024 · To calculate the area of an equilateral triangle, you only need to know the side: area = a² × √3 / 4. Since √3 / 4 is approximately 0.433, we can formulate a quick recipe: to approximate the area of an equilateral triangle, square the side's length and then multiply by 0.433. Although we didn't make a separate calculator for the ...
