Two transformations that can be used to show that polygon ABCDE is congruent to polygon GFJIH : <u>rotation -90° and translation (0,2)</u>
<h3>Further explanation</h3>There are several forms of transformation, including translation, dilation, rotation or reflection
There are 2 shapes of geometry:
Similar figures:
the same shape but different in size,
Congruent figures:
the same size and the same shape
Both polygons will appear congruent if, after being transformed, the two polygons will map exactly to each other
A sequence of two transformations e can do is :
1. rotation -90°
Let point H(4,1) from polygon GFJIH , we rotate -90°
2. translation (0,2)
Keywords: transformation, translation, rotation

<em>Greetings from Brasil...</em>
As we have a line, the function will be given by the expression:
F(X) = AX + B
where
<em>A = ΔY/ΔX</em>
<em>B = where the line intersects the Y axis</em>
Looking at the graph we have already concluded that
B = - 3
A = ΔY/ΔX
A = (5 - 3)/(4 - 3) see attached picture
A = 2
So,
F(X) = AX + B
<h2>F(X) = 2X - 3</h2>
