Which transformations can be used to prove that this figure is symmetrical?
A heart with center point A. Line r splits the heart in half. Transformation 1:
Rotate the figure 180°
around point A.
Transformation 2:
Reflect the figure
across line r.
CLEAR CHECK
Applying Transformation 1 twice carries the figure onto itself.
Applying Transformation 2 carries the figure onto itself.
Applying Transformation 1 carries the figure onto itself.
Both transformations must be applied to carry the figure onto itself.
1 answer
Both transformations, Transformation 1 (rotate the figure 180° around point A) and Transformation 2 (reflect the figure across line r), can be used to prove that the figure is symmetrical. Applying either transformation carries the figure onto itself, indicating that it is symmetrical.
