Unit 9 transformations homework 4 symmetry answer key
Question:
Which figure has just rotational symmetry?
Answer:
Rotational symmetry is when a shape looks the same when it is turned around a central point by less than 360°. In geometry, a shape has rotational symmetry if it looks the same when turned just a little bit. It’s also known as radial symmetry. The number of ways an object can be turned and still look the same is its degree of rotational symmetry. When a shape can be turned around a central point and still look the same, this is called “rotational symmetry.” Many shapes, like squares, circles, regular hexagons, etc., have rotational symmetry.
