<u>Answer:</u> There are 20 sides of a given regular polygon.
<u>Step-by-step explanation:</u>
To calculate the sides of a regular polygon, we use the equation:
We are given:
Smallest angle of rotation =
Putting values in above equation, we get:
Hence, there are 20 sides of a given regular polygon.
Answer: Yes
Step-by-step explanation:
Since ABCD is a rectangle, , , , and are all right angles, and are thus all congruent because all right angles are congruent. Furthermore, because ABCD is a rectangle, we know that and . Because we are given that X, Y, Z, and W are midpoints, using the fact that halves of congruent segments are congruent, we can conclude that and that . As a result, we can conclude that by SAS, and thus by CPCTC, . Therefore, since the quadrilateral formed by the midpoints has four congruent sides, it must be a rhombus.
