How many pairs of parallel lines does a decagon have?
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
Are all regular decagons similar?
Yes, all regular decagons are similar because they have the same shape but can differ in size. Similarity in polygons means that corresponding angles are equal and the lengths of corresponding sides are proportional. Since all regular decagons have equal angles (144 degrees) and their sides are all the same length relative to their size, any regular decagon can be transformed into another through scaling.
How many sides do 2 nonagons and 2 decagons have in all?
38 sides
How many sides do 1 pentagon and 4 do decagons have in all?
A pentagon has 5 sides, and a decagon has 10 sides. Therefore, 4 decagons would have (4 \times 10 = 40) sides. Adding the sides together, 1 pentagon and 4 decagons have a total of (5 + 40 = 45) sides.
