The coordinates of the vertices after the reflection over the x-axis are A' (2, -3) B' (4, 5) and C' (-1, -2)
Given,
A triangle ABC with vertices A(2,3) , B(4,-5), and C(-1,2)
To find the coordinates of the vertices of each figure after a reflection over the given axis.
Now, According to the question:
We should know that:
You should know that you can predict changes in coordinates after translations without a graph or anything like that.
(x, y) reflected over the x axis = (x, -y)
(x, y) reflected over the y axis = (-x, y)
(x, y) rotated 90 degrees around the origin = (y, -x)
(x, y) rotated 180 degrees around the origin = (-x, -y)
(x, y) rotated 270 degrees around the origin = (-x, y)
So here's our set of points.
A(2,3) , B(4,-5), and C(-1,2)
Here's those points reflected over the x axis.
A' (2, -3) B' (4, 5) and C' (-1, -2)
Hence, The coordinates of the vertices after the reflection over the x-axis are A' (2, -3) B' (4, 5) and C' (-1, -2)
