Triangle ABC is reflected over the y-axis what are the coordinates of the reflected triangle describe in words what happens to the x coordinates and the y coordinates of the original triangle's vertices as a result of this reflection.
@Steve explain why and what you mean! How can we experiment with just two words change sign... what should we draw a pretty pony and expect an A+ out of that? Also I am not being rude I am being nean-raven teen titans go.
To find the coordinates of the reflected triangle when triangle ABC is reflected over the y-axis, you need to remember that reflecting a point over the y-axis negates the x-coordinate while keeping the y-coordinate the same.
Let's say the coordinates of triangle ABC are:
A: (x1, y1)
B: (x2, y2)
C: (x3, y3)
When triangle ABC is reflected over the y-axis, the coordinates of the reflected triangle, let's call it A'B'C', can be found as follows:
A': (-x1, y1)
B': (-x2, y2)
C': (-x3, y3)
In words, the x-coordinates of the original triangle's vertices are transformed by changing their signs, while the y-coordinates remain unchanged.
To find the coordinates of the reflected triangle, you need to understand the concept of reflection. When a shape is reflected over the y-axis, the x-coordinates change their signs, while the y-coordinates remain the same.
Let's say the original triangle ABC has the coordinates (x1, y1), (x2, y2), and (x3, y3) for its vertices A, B, and C, respectively.
When reflecting over the y-axis, the x-coordinates change their signs, meaning the new x-coordinates will be the opposite of the original ones. So the reflected triangle's vertices will have coordinates (-x1, y1), (-x2, y2), and (-x3, y3).
In words, the x-coordinates of the original triangle's vertices change from positive to negative, while the y-coordinates remain the same.
x values change sign.
y stays the same
try experimenting with this -- it should be quite clear.
