Math Problem Statement
Write the coordinates of the vertices after a rotation 180° counterclockwise around the origin.
Solution
You provided an image that asks for the coordinates of the vertices after a 180° counterclockwise rotation around the origin. Here's how we can solve this step by step.
Current coordinates of the vertices:
Looking at the grid, the original coordinates are:
Rule for a 180° counterclockwise rotation:
For a 180° rotation around the origin, the rule is: This means we change the sign of both the x and y coordinates.

Would you like a deeper explanation or have any other questions? Here are some related questions for further practice:
- What is the rule for a 90° clockwise rotation around the origin?
- How would the coordinates change for a 270° counterclockwise rotation?
- What would happen to the shape if it were reflected across the x-axis instead of rotated?
- How does the area of the figure change after a rotation or reflection?
- What are the coordinates after a 360° rotation, and why?
Tip: When performing rotations, make sure to apply the rules consistently to all points, and check how the figure moves in relation to the origin.
