Tostate:the magnitude of the rotational symmetry of the figure and express the answer in degrees.
Answer to Problem 11STP
The center is the intersection of the diagonals.
Explanation of Solution
Given:
Concept used:
It is in symmetry a figure exists if there is a reflection, rotation, or translation that can be performed and the image is identical. Rotational symmetry exists when the figure can be rotated and the image is identical to the original.
Regular
Order of the rotation:
A figure has rotational symmetry if it coincides with itself in a rotation less than 360 degrees.
The order of rotation of a figure is the number of times it coincides with itself in a rotation less than 360 degrees.
The
Calculation:
If the figure has rotational symmetry and if so, give the order of symmetry, the figure has order
Hence, the center is the intersection of the diagonals.
