When a figure is translated reflected or rotated what is the same about the original figure and its image?
It still has the same weight. Even turned or reflected the weight/mass remains the same.
What figure has rotational symmetry but not line symmetry?
A figure that has rotational symmetry but not line symmetry is a figure that can be rotated by a certain angle and still look the same, but cannot be reflected across a line to create a mirror image of itself. An example of such a figure is a regular pentagon, which has rotational symmetry of 72 degrees but does not have any lines of symmetry. This means that if you rotate a regular pentagon by 72 degrees, it will look the same, but you cannot reflect it across any line to create a mirror image.
How many orders of symmetry does a rectangle have?
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
What is congrunent?
If a shape is congruent to another, it means both shapes are exactly the same (one might have been rotated around slightly, but it is still the same shape).
How many order of rotational symmetry does a circle have?
The order of rotational symmetry for a circle is infinite. This is because it can be rotated any amount from the middle and it will still look the same. You can use a special sign to show this: ∞
