Fluency & Practice
Answer all questions. Show your working in the grid spaces provided.
1.
Plot the point (3, 4) on the grid. Rotate it 180° about the origin. What are the new coordinates?
[2 marks]2.
Calculate the coordinates of the point (-5, 2) after a 180° rotation about the origin.
[2 marks]3.
If point (x, y) rotates 180° about the origin and results in (-x, -y), what is the image of the point (7, -3)?
[2 marks]4.
Construct the point (2, -5), then rotate it 180° about the origin on the grid.
[2 marks]B
Problem Solving & Reasoning
Answer all questions. Show detailed reasoning and steps.
1.
A triangle has vertices at A(1, 2), B(3, -4), and C(-2, 5). After rotating the triangle 180° about the origin, what are the new coordinates of each vertex? Explain the reasoning.
[4 marks]2.
A point P is at (x, y). If rotating it 180° about the origin results in the point (-x, -y), what is the original position of P if its image is at (6, -8)?
[3 marks]C
Real-world Applications
Answer all questions. Use the grid to visualize transformations if needed.
1.
In a game, a character at position (4, -3) is rotated 180° about the origin to find its new position. Where does the character end up? How does understanding this rotation help in planning game movements?
[4 marks]D
Challenge & Extension
Answer all questions. These are designed to challenge your understanding of rotation about the origin.
1.
Construct a triangle with vertices at (1, 2), (4, 5), and (7, 2). Rotate the entire triangle 180° about the origin. What are the new vertices? Prove your construction.
[4 marks]2.
A point (x, y) is such that after a 180° rotation about the origin, it coincides with the point (x, y). What are the possible coordinates of such points? Explain.
[3 marks]E
Mixed Review & Error Analysis
Answer all questions. Review common mistakes and learn from them.
1.
A student claims that rotating (3, -7) 180° about the origin gives (3, -7). Is this correct? Why or why not? Correct the mistake if necessary.
[3 marks]2.
Common mistake: A student believes that rotating a point (x, y) 180° around the origin results in (x, y). What is the actual image? Explain why.
