Does a pentagon have 2 right angles?
AnswerIn a regular pentagon, there are no right angles. A regular pentagon is one that has 5 equal sides and 5 equal angles. The sum of the 5 angles is 540 degrees. This is found by subtracting 2 from the number of sides and multiplying by 180 degrees. For a regular pentagon the formula would be (5 - 2) * 180 = 540. This works for all polygons. Just replace the 5 with the number of side in the polygon. A good website to visit for this is http://regentsprep.org/Regents/math/poly/LPoly1.htm.A non-regular pentagon can have right angles. Home plate on a baseball field would be an example.Original Answer Nope, it has 5 angles of 72 degrees each.sorry just make it simple always take 180 degrees and divided by the # of sides it will always give you the correct cut angle to make a angle frame exmp 180 degrees / by 8 = 22.5 that cut would give you a octagone. so for a equal sided polygon always divide the 180 degrees by the # of sides. so for a pentagon the cut would be 36 degrees on each end which = 72 degrees 72 X 5 (sides) = 360 degrees
Is a concave equilateral pentagon possible?
No, a concave equilateral pentagon is not possible. In a concave polygon, at least one interior angle must be greater than 180 degrees, which would make it impossible for all sides to be of equal length while maintaining the necessary geometric properties of a pentagon. Thus, an equilateral pentagon must be convex.
Describe the conditions that make a polygon a regular polygon?
All sides must be equal in length and each interior angle must be equal in degrees
How many parallel sides does a pentagon?
None, for a regular pentagon. Not all pentagons are necessarily regular (all sides and angles the same). You can make a pentagon with 2 pairs of parallel lines. Take a square, and cut off one corner. Now you have a 5-sided polygon (pentagon) with 2 pairs of parallel sides.
Is there a pentagon with no symmetry?
Yes. Just make the sides each different lengths to make it irregular.

Draw a pentagon no equal sides?
Make sure that the sides go in order from either 1-9 or 2-10.
What is the angle of rotation in a pentagon?
Well, honey, a pentagon has five sides, so the angle of rotation would be 360 degrees divided by 5, which gives you 72 degrees. So, if you want to twirl that pentagon around, just make sure to do it in 72-degree increments. Now go impress your friends with that little nugget of geometry knowledge!
Is a pentagon a regular or irregular shape?
It depends! If all its sides and angles are the same then it is a regular pentagon, however, if it's a five sided shape (5 straight sides that join to make a single shape), but it's sides or angles are not equal then it is an irregular pentagon.
What are three attributes of a square?
The sides are equal The angle between adjacent sides is 90 degrees There are two diagonals The diagonals are equal in length The diagonals make 90 degrees with each other The diagonals make 45 degrees with the sides
Does a pentagon make 5 equilateral triangles?
A regular pentagon (one where all sides are equal and all central angles are equal) will not form five equilateral triangles (five triangles of equal side length). The reason is if you make a point in the very centre of the pentagon and were to draw a line to each of the outside corners you would end up with five triangles, but if you look solely at the centre point you would see all of its surrounding sides have angles. This means that the sum of all those interior angles you just made would be 360 degrees (a full circle). Now if you divide that by the five segments you discover that each of the interior angles (the ones around the centre point) are actually 72 degrees. Then using the knowledge that triangles have 180 degrees, you find that the other angles of your five triangle sections are actually 54 degrees. An equilateral triangle would have all sides equal and all of its angles would be 60 degrees. This is not the case here and if you do some further math you discover that the outside sides of the pentagon are longer than the sides of your triangle segments as a result (they're actually an isosceles triangles). If you can find the area of one triangle segment then you can get the area of the pentagon, this is just something to keep in mind when you're finding the area. Hope that's alright, I literally just finished a question like this in my homework.
What does an equilateral shape look like?
The term equilateral means "having the same length or measure" as we apply it. There are a number of shapes that meet this criterion. The equilateral triangle, the square, the regular pentagram, the regular hexagram and on and on in the polygon shapes. Note that the term "regular" is applied. A "regular pentagon" is a pentagon with all sides having equal length. We usually don't say "an equilateral pentagon" in geometry, but us the term "regular pentagon" instead. It communicates the same information. That's it in a nutshell. Next time you hear the word pentagon or octagon, make sure you don't assume it to be a regular one (though it may very well be). Where data is lacking, ask a question or investigate. Either that or make allowances for the possibility that the polygon may be regular or may not be.
Can you make pentagon with unequal sides that has 2 lines of symmetry?
No you cannot.
How do you make a tetrahedron?
you can use your favorite 3d creation program of your choice, i prefer Rhino, or Alebra. Make a pentagon, copy, and rotate the sides from the center of the first pentagon exactly 63.43 degrees or the complementary of that angle. Its really easy because then you just mirror that second pentagon onto the other sides of the first pentagon. If you want a more elaborate explanation, go look for another tutorial on some site, maybe youtube if your lucky. Sorry but there you go.
