Answer:
1. A regular star pentagon, {5/2}, has five corner vertices and intersecting edges, while concave decagon, |5/2|, has ten edges and two sets of five vertices.
2. A rectangle is a 2D shape in geometry, having 4 sides and 4 corners. Its two sides meet at right angles. Thus, a rectangle has 4 angles, each measuring 90 ̊. The opposite sides of a rectangle have the same lengths and are parallel.
3. Futility Closet recently posted a nice puzzle about the sum of the angles in the “points” of a star polygon. It's easy to show that the five acute angles in the points of a regular star, like the one at left, total 180°.
