b) Write a rule for the translation. Use arrow notation.
c) Write the coordinates of the vertices of the new image after translation.
The coordinates of the vertices of the new image after translation and reflection :
A''(0, 1); B''(-3, 3); C''(-2, -1).
A reflection is an example of a transformation
Reflection is the process of mirroring each point on the geometry of a certain line.
The original figure is called the pre-image and the final figure is called the image
The image will be congruent with the pre image and the distance from the image to the mirror axis is the same as the distance from the pre image to the mirror axis
• The equation of reflection across the y-axis
x '= -x
y '= y
can be written
While the transformation itself is the displacement of the object given a distance and direction (for example up or down)
So each point is moved in the same distance and direction
Can be formulated :
Triangle ABC below is reflected across the y-axis and then translated 1 unit right and 2 units down.
So the stages
1. reflected across the y-axis first and then
2. translated 1 unit right and 2 units down.(T(a,b) ⇒a=1,b=-2)
Coordinate A(1,3),B(4,5),C(3,1)
reflected becomes :
A(1,3)⇒A'(-1,3)
B(4,5)⇒B'(-4,5)
C(3,1)⇒C'(-3,1)
A'(-1,3) ⇒A''(-1+1,3-2)⇒A"(0,1)
B'(-4,5) ⇒B''(-4+1,5-2)⇒A"(-3,3)
C'(-3,1) ⇒ C"(-3+1,1-2)⇒C"(-2,-1)

Answer:
Length of the rectangle is = 8 inches.
Step-by-step explanation:
Given :
Area of square = Area of the rectangle
According to the question:
Length of the square be 'x'.
Its area = (Side)*(Side) = ...equation (i)
Length of the rectangle =
Width of the rectangle =
Area of the rectangle =Length * Width
⇒
⇒ ...equation (ii)
Equating both the equation as area of both the figure are equal.
⇒
⇒ ...subtracting both sides
⇒ ...dividing both sides with 2
⇒ inches
Plugging the value of x=4 in the length of the rectangle.
We have,
⇒
So the length of the rectangle = 8 inches.
