04 Pembelajaran 1 : Refleksi
Neque porro quisquam est qui dolorem ...

Percobaan 4

1. Make points on the Cartesian coordinate plane, those points are A (4, 1);

B (2, 5); C (-2, 5); D (1, -1); dan E (-2, -3).
2. Then reflect the points on the line y = -x.

3. Determine the image point of each point reflected on the line y = -x.

4. Record the experimental results in the following table:

No Coordinate point Reflection Shadow
against coordinates

1. A (4, 1)

2. B (2, 5)

3. C (-2, 5)

4. D (1, -1)

5. E (-2, -3)

5. Analysis of the results of observations by paying attention to the pattern of

coordinate points and shadow coordinates.

6. Write down what conclusions you get after carrying out the experiment.
