a Pentagon is five sided and CAN have 3 right angles.
The total sum of angles of an n-sided shape is (n-2)x180o Hence, the angles in a five sided shape add up to (5-2)x180o = 3 x 180o = 540o
A heptagon.
A scalene triangle.
A 14-sided and 3-dimensional shape is called either a tetrakaidecahedron or tetradecahedron. This 14-sided polyhedron can have six quadrilateral and eight hexagonal faces.
