Math Problem Statement
The rule T1, -4 CompositionRO, 180°(x, y) is applied to rectangle KLMN.
On a coordinate plane, 5 rectangles are shown. Rectangle K L M N has points (3, negative 4), (3, negative 1), (5, negative 1), (5, negative 4). Rectangle 1 has points (negative 4, 6), (negative 4, 4), (negative 1, 4), (negative 1, 6). Rectangle 2 has points (0, 0), (negative 2, 0), (negative 2, 3), (0, 3). Rectangle 3 has points (negative 2, 0), (negative 4, 0), (negative 2, negative 3), (negative (4, negative 3). Rectangle 4 has points (1, 0), (4, 0), (1, 2), (4, 2). Which rectangle shows the final image?
1 2 3 4
Solution
The transformation rule provided is T1, -4 CompositionRO, 180°(x, y). This rule combines two operations:
- Translation (T1, -4): This means the rectangle is translated (shifted) 1 unit to the right and 4 units down.
- Rotation (RO, 180°): This means the rectangle is rotated by 180 degrees around the origin (0, 0), which effectively flips it both horizontally and vertically.
Step 1: Apply the Translation (T1, -4)
The original rectangle KLMN has vertices at:
Applying the translation , we add 1 to the x-coordinates and subtract 4 from the y-coordinates:
- New
- New
- New
- New
So, after the translation, the new vertices are: , , , and .
Step 2: Apply the 180° Rotation
The 180° rotation around the origin transforms the point into . Applying this to each of the translated points:
- Rotate to
- Rotate to
- Rotate to
- Rotate to
So, the final vertices after the 180° rotation are , , , and .
Step 3: Compare with Given Rectangles
Now, we compare these final coordinates with the given rectangles:
- Rectangle 1 has vertices at . This does not match.
- Rectangle 2 has vertices at . This does not match.
- Rectangle 3 has vertices at . This does not match.
- Rectangle 4 has vertices at . This does not match either.
Since none of the given rectangles match the final transformed coordinates , it appears there may be a misunderstanding or discrepancy in the problem description or a mislabeling of the options. However, based on the transformation procedure, the correct final image should be found by visually matching this shape with the options provided.
