A^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
Answer:
Coordinates switch, and the new y-coordinate changes sign
Explanation:
We have point A with the coordinates (-1,2), when we rotate it c90º it becomes (2,1).
What happened? The coordinates switched and the x-coordinate of A (-1) became the y-coordinate of A' (1) and it changed its sign.
Step-by-step explanation:
None of these,
a(under root),a, a(square)
this is the correct answer
