Polygons & Solids
in Real Life Pentagon Octagons 3-D Polygons
in Real Life A pentagon is a five sided polygon. A regular pentagon has 5 congruent sides and
angles. The sum of the interior angles is 540 degrees, and the sum of the exterior angles is 360 degrees. Octagons are 8 sided polygons. The sum of the interior angles is 1080 degrees, and the exterior angles sum is 360 degrees. Rectangular prism- 3-D shape of a rectangle.
Cylinder- 3-D shape of a rectangle and a circle(base).
Pyramid- 3-D shape of a triangle, and another polygon(base).
Cone- 3-D shape of a triangle, and a circle(base).
Sphere- 3-D shape of a circle. By: Tucker Penny What is a Polygon? A polygon is a plane figure
with at least three straight sides and angles. Triangles A triangle is a 3 sided figure, whose interior angles have a sum of 180 degrees, and the exterior angles add up to 360 degrees. Quadrilaterals A quadrilateral is a
4 sided figure. The sum of the interior and exterior angles are 360 degrees. Some types are square, rectangle, rhombus, trapezoid, and kite. Hexagon A hexagon is a 6 sided figure, with interior angles of 720 degrees total, and exterior angles add up to 360 degrees.

rectangles are similar . I don't know why the quarter is there Product that's a Polygon Square/Rectangular Picture Frame The shape for a picture frame
is much better than other shapes. Here are some reasons why: First of all, this picture frame includes all of the picture. Other picture frames with different shapes have to cut off some of the picture. Also, this shape of a picture frame is easier to measure dimensions of the frame. Other shapes don't have corners even with each other. Plus, some people might not like the design of a circle picture frame. The look of it does not appeal to some people. The square picture frame can have multiple pictures in it at once, too. The circle ones, most aren't designed to have more than 1 picture in each frame. The square picture frames, are more inexpensive than circle ones, as well. This way more people will buy it, and there will be more profits.
