Answer:
Step-by-step explanation:
1.Draw a mirrorline across y = 1 (Another way of saying that is draw a horizontal line through where y = 1)
2.For every single point of the shape, count the number of squares away that is from the mirror line on the graph, and from the mirror line go downwards by the amount of squares that you just counted from the mirrorline. Finally plot that point you reached with a cross and do the same with every point of the shape
3. Join all the cross together and there is your reflected shape.
*Extra Information*
If this was x = 1 instead of y = 1 you would reflect the shape horizontally instead of vertically (Youll see what i mean when the shape is reflected)
The new coordinates are (2, -2), (4, -2), and (2, -5) after reflection over y = 1
What is geometric transformation?
It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have vertices of the triangle shown in the picture.
The reflection over y = 1
(x, y)-->(x, 2 - y)
(2, 4)-->(2, -2)
(4, 4)-->(4, -2)
(2, 7)-->(2, -5)
Thus, the new coordinates are (2, -2), (4, -2), and (2, -5) after reflection over y = 1
