Describe the series of transformations that occur have occurred to move the triangle and quadrant 4 to the each triangle in quadrant two to show that the triangles are congruent.

Original position was G (-5, 5) E (-1, 3) H (-5, 3)
New position is G (3, 3) E (7, 1) H (3, 1)

In order to show that the triangles in quadrant two are congruent to the original triangle in quadrant four, a series of transformations can be applied.

1. Translation:
The original triangle is translated to the right by 8 units and down by 2 units. This moves point G from (-5, 5) to (3, 3), point E from (-1, 3) to (7, 1), and point H from (-5, 3) to (3, 1).

2. Reflection:
After the translation, a reflection is performed over the y-axis. This flips the triangle horizontally while maintaining the same orientation. As a result, point G is now (-3, 3), point E is now (-7, 1), and point H is now (-3, 1).

3. Rotation:
To align the triangle with quadrant two, a rotation of 180 degrees is applied around the origin. This rotates the triangle counter-clockwise and brings it into the second quadrant. After the rotation, point G becomes (3, 3), point E becomes (7, 1), and point H becomes (3, 1).

By applying these transformations (translation, reflection, and rotation) in sequence, the original triangle can be transformed into the congruent triangle in quadrant two.
