A regular decagon has 10 sides. How many reflectional symmetries does a regular decagon have?
lina2011 [118]

The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.

For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.

There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.

MariettaO [177]

Answer:

sorry to answer late but..

Step-by-step explanation:

\frac{1}{75} cm = \frac{scale }{real}

the wings of the real plane are 12 meters or 1200 cm

we want to solve for the scale, sooo do the algebra...get scale by it self..

real * \frac{1}{75} = scale

1200 * \frac{1}{75} = 16

The scale model wings are 16 cm   2.54 cm is one inch so the wings are approx.  6.3 inches

5 x 5 = 10 x 5= 20 x 5 = Answer these 3 problems and then tell how they are<br> related.
viva [34]

Step-by-step explanation:

First we need to find out what they all 3 equal, with multiplication.

5×5=25

10×5=50

20×5=100

In each of these problems, the answer is multiplying itself by 2 in order to get to the next answer. So this is how they are related
