text: A decagon is called regular when its sides are equal and also its interior angles are equal.
text: Regular decagons have equal interior angles, by definition.
text: In the internal triangle, that is formed by two successive diagonals and the edge of decagon, the two angles adjacent to the edge, are equal to 72°.
text: Each angle in a regular decagon is equal to 144°.
text: Each angle in a regular decagon is equal to 144°.
text: so we know then that all interior angles and sides are equal.
text: If each angle is equal, then each angle is 144,000 degrees.
text: In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
text: All edges and internal angles are equal.
text: The regular dodecahedron represents a special intermediate case where all edges and angles are equal.
text: Continuing from there in that direction, we pass through a degenerate case where twelve vertices coincide in the centre, and on to the regular great stellated dodecahedron where all edges and angles are equal again, and the faces have been distorted into regular pentagrams.
text: The final part of the above answer is only true if all the angles of the decagon are equal.
text: But there is no justification for assuming that the angles are all equal.
text: The interior angles of the decagon is equal to (n-2)*180, where n is equal to no.of sides
text: As per above each angle is equal to 144 degrees, so we know that on a straight line the angle is equal to 180 degrees
text: Each angle in a regular dodecagon is equal to 150°.
text: One interior angle of the decagon is equal to two of these angles, so the answer is 144 degrees.
text: Regular figures are really easy to work with because their sides and angles are all equal.
text: For any polygon, if you join the vertices to the center, angle between any two adjacent radii will be equal to "360/n Degrees".
text: Keep in mind the decagon must be regular which mean the sides are all congruent and the angles are all equals.
text: A regular decagon has ten equal sides and equal angles.
text: A regular decagon has ten equal sides and equal angles.
