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.
Please help! Thank you!
A'(-1, 3) B'(-4, 5) C'(-3, 1)
@Steve
No offense, but your attitude isn't cool. If you're going to be a helper, be nice about it instead of making people feel dumb. If you don't want to help, that's okay, too. Basically, be nice. :)
Just help the poor person...and me ;)
Can someone please help me?
Anyone please!!!
Can someone please help me? Anyone?
Is ↑ right someone check plz
feel dumb **
it tags out- dump with a b **
is steve right
help!!!1
Yes, Steve is right. When a triangle is reflected over the y-axis, the x-coordinates of its vertices are negated while the y-coordinates remain the same. For example, if the original coordinates of triangle ABC are A(x1, y1), B(x2, y2), and C(x3, y3), then the reflected coordinates of triangle A'B'C' would be A'(-x1, y1), B'(-x2, y2), and C'(-x3, y3).
describe in words what happens to the x-coordinates and y-coordinates of the original triangles vertices as a results of this reflection
When a triangle is reflected over the y-axis, all of its x-coordinates are negated, while the y-coordinates remain the same. This means that if a point P on the original triangle has coordinates (x, y), its reflected point P' on the new triangle would have coordinates (-x, y).
They are right i took the test
reflection through the y-axis changes the sign of the x-coordinate.
Surely your text explains this.
Or, you could get out some graph paper and do some experimenting. Just plot a point and flip it over the y-axis.
