![]() ![]() These steps also include 'pit stops' to complete fun geometry projects and coloring sheets. The seven steps detailed bellow take you from basic identification all the way through to taking a detailed look at the theorems involving the pentagon shape. You can investigate Regular Polygons in a little more detail another time. But a Pentagon is ANY shape composed of 5 intersecting lines.Ī regular pentagon is a 5 sided shape where ALL lines are the same length and ALL angles are equal in size. I feel the reason for this is that the shape above is a Regular Pentagon, but most kids learn to identify it as simply a Pentagon. But what catches most elementary students out at some point are the two terms - Pentagon and Regular Pentagon. look out Nico and Nia! Phew! I'm glad they are okay! "Yes! Now we get to keep all the toys!" "You're such a gem, Nia.The Pentagon Shape is one of the shapes your Kindergartner learns to identify as part of their math curriculum. Oh, the claw machine picked up a soccer ball! Uh oh, I think the claw might be too sharp to hold that. In order for a shape to be identified as a pentagon, it must have ALL of the defining attributes: five straight sides (.) five corners (.) and be fully closed. Remember (.), a pentagon is a polygon with five sides. Last, we see a gemstone sticker (.) what a treasure! Is this shape a pentagon? (.) It has five sides, (.) five corners, (.) and is fully closed! It has ALL the defining attributes! This shape IS a pentagon, so Nico and Nia get to keep this prize! Before we see if Nico and Nia will get more prizes, let's summarize. The headband does not have ALL the defining attributes, so it is NOT a pentagon. ![]() Is it fully closed? (.) It is NOT a closed shape. How many corners are there? (.) There are FOUR corners. Next, we see a headband (.) is it a pentagon? (.) It has FIVE sides, (.) and they are all straight. Remember, in order to be a pentagon, it must have ALL the defining attributes. Even though this shape has one of the defining attributes, it is NOT a pentagon. Is it fully closed? (.) Yes, it is a fully closed shape. How many corners? (.) There are FOUR corners. Now that we know the attributes of a pentagon, let's help Nico and Nia identify pentagon prizes in the claw machine! The first prize they've picked is a bubble fidget toy (.) is it a pentagon? Let's check (.) how many sides does it have? (.) It has FOUR straight sides. THIS shape is a pentagon because it has five straight sides (.) five corners (.) and is fully closed. A POLYGON, is a two-dimensional shape that is made of straight lines and is fully closed. Shapes are figures that we can name based on their defining attributes, or traits that make them unique. ![]() "What is a Pentagon?" A pentagon is a special type of shape. Let's help Nico and Nia identify pentagons in the claw machine by answering the question. Nico and Nia are at the arcade and just found their favorite game (.) the claw machine! However, this is a special kind of claw machine (.) it only releases prizes that are shaped like a pentagon. In order for a shape to be identified as a pentagon, it must have ALL of the 3 defining attributes: Pentagons can be defined by three attributes. This shape is a pentagon! Pentagons – SummaryĪ pentagon is a five-sided polygon. Is this shape a pentagon? Let’s take a look at the attributes. That means all sides must meet to make corners or angles, without leaving any sides open. Pentagons must also have one last attribute. There is one more attribute a shape must have in order to be classified as a pentagon. However, it’s not just about the pentagon sides, it must have two more attributes as well! How Many Angles Does a Pentagon Have?Ī pentagon must also have five corners, which are also referred to as angles. In other words, a pentagon has how many sides? In order for a shape to be classified as a pentagon it must have five straight sides. Now that we know what polygon has 5 sides, let’s answer some questions about pentagons. ![]()
