How many reflection symmetries does a five-pointed star have?

Mathematics
1 answer:
RSB [31]3 years ago
8 0

Answer:

a 5-point star has rotational symmetry. A 5-point star is a two-dimensional polygon in the shape of a star with five points, or tips.

So symetry will have a total of 360 degrees, then if you divide it by 5 ( the number of point in the star) you will get 72 degrees each so it has 5 reflections

Select three ratios that are equivalent to 11:111:111, colon, 1.<br> Choose 3 answers:
kirill115 [55]

The three ratios that are equivalent to the given ratio are options B, C and E.

<h3>How to determine the equivalent ratios?</h3>

In order to determine the ratios that are equivalent to the given ratio, we would evaluate by dividing each of them by their respective denominator value:

(11:111:111)/1 = 11:111:111.

For choice A, we have:

1:111:111/11 = 1/11:111:111 (not equivalent).

For choice B, we have:

22:222:222/2 = 11:111:111. (equivalent).

For choice C, we have:

55:555:555/5 = 11:111:111. (equivalent).

For choice D, we have:

9:999:999/99 = 1/11:111:111 (not equivalent).

For choice E, we have:

110:1110:1110/10 = 11:111:111. (equivalent).
