10 sides and 10 angles
A polygon with 10 sides and 10 angles is called a decagon.
10 angles
There (not their) are 10 angles.
10 angles
A square has 4 angles, so ten squares have 10*4 = 40 angles.
A decagon has 10 sides, and 10 angles. The sum of the interior angles of a decagon is (10-2)×180° = 1440° In a regular decagon all the angles are congruent at 1440° ÷ 10 = 144°
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
no a star has 6 angles
No. A heptagon has 7 sides, so it has 7 angles; thus it cannot have 10 right angles.
A decagon has 10 angles (and sides)
10 rays can meet in 45 vertices. At each such vertex there will be 4 angles which makes 180 angles in all.
