This is the formula of finding the hypotenuse: a² + b² = c².

So the legs would be a and b.

4² + 4² = c²

Which statement accurately describes how to perform a 90° clockwise rotation of point A (1,4) around the origin?
pochemuha

Answer:

B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90  clockwise

Step-by-step explanation:

This is because, to locate a point rotated by 90° from point A, we first draw a circle with the origin as its center and a radius of the origin and point A. We then locate a point on the line that is 90° clockwise from point A. For a 90° clockwise rotation, for a given pair of coordinates, (x,y), the resulting pair of coordinates is (y,-x). So, for the coordinates (1,4), the resulting coordinates we are looking for is (4, -1), which is the point rotated 90° clockwise from point A. The point is thus (4,-1).
