NO, a circle is not a polygon. A polygon is composed of a finite set of straight line segments, and a circle has NO straight line segments.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Are polygons the same things as shapes?

yes. polygons are closed shapes with no curves. i.e. circles are not polygons, squares are, triangles are, ect

Are circles and ovals polygons?

no straight sides

How are circles and rectangles alike?

They're both polygons and shapes.

Are all circles regular polygons?

A circle is not a polygon, so no.

Why are circles not polygons?

a polygon has all closed sides and no curved sides

Which property do the circles polygons have in common?

They are closed 2-dimensional shapes.

Which figures are always similar in geometry?

Circles and all regular polygons.

Which shapes are polygons and which are not?

A polygon is a two-dimensional shape enclosed by lines only, not curves. So triangles, squares, rectangles, and octagons are examples of polygons. Circles, ellipses, and annuli are some shapes that are not polygons.

What are 4 things polygons have in common?

Your quesion makes no sense. Please elaborate, and i will do my best to provide an answer. You need to tell me what your are comparing polygons to. Ex: What are 4 thing polygons and CIRCLES have in common. your sentence lacks that.

A diagram included five hexagons eleven circles six decagons nine squares and eleven lines How many polygons are in the diagram?

There are 20.5 + 6 + 9 = 20 (Neither circles nor unclosed linear shapes are polygons.)

Name types of polygons?

Some examples of polygons include circles, triangles, squares, rectangles, pentagons, and hexagons. These are examples of 'simple polygons,' in that none of the lines overlap and intersect each other, such as in a pentagram, which is a 'star polygon.'

What shapes have no right angels and no equal sides?

Circles, some triangles, and irregular polygons

Why is a cylinder not a polyhedron?

A polyhedron is a 3 dimensional figure made of polygons. A cylinder is made of two circles and a rectangle around the middle. Since circles are not considered polygons (don't have straight edges), a cylinder cannot be a polyhedron. I just had a discussion about this with my math students today.

What shapes cannot tesselate?

There are many shapes: circles, ellipses, ovals (elongated circles), cardioids, any shape with a "hole" in it such as a annulus.Polygons will tessellate if combined with other suitable polygons.

What is the repeat unit of design for Islam?

The four basic shapes, or "repeat units," from which the more complicated patterns are constructed are: circles and interlaced circles; squares or four-sided polygons; the ubiquitous star pattern, ultimately derived from squares and triangles inscribed in a circle; and multisided polygons.

What ancient Greek mathematician came up with an approximate value for pi by circumscribing and inscribing circles in and around regular polygons?

Archimedes (287-212 BC) was the first to estimate π rigorously. He realized that its magnitude can be bounded from below and above by inscribing circles in regular polygons and calculating the outer and inner polygons' respective perimeters. By using the equivalent of 96-sided polygons, he proved that 310/71< π < 31/7. The average of these values is about 3.14185.

What is the word that describes precise shapes or forms such as circles squares or triangles.?

They are geometric shapes called polygons

What is the formulae for area?

Depends on the shape. There are different formulae for different shapes: triangles, quadrilaterals, regular polygons, circles, ellipses.

What shape could not have parallel lines?

Triangles, Circles, Ellipses Only triangle if you only want polygons.

How do you work out a perimeter?

for polygons, add up the lengths of all the sides. for circles, multiply the diameter of the circle squared by pi (3.14)

How are prisms and cylinders different?

Prisms have polygons as bases whereas cylinders have circles as bases. In a way, a cylinder is like a circular prism.

What shapes do not tessellate?

Shapes such as circles, regular pentagons, and heptagons.Most regular polygons will not tessellate on their own. Only triangles, squares and hexagons will.With irregular polygons there is more of a choice. All isosceles or scalene triangles, parallelograms, trapeziums and kites will tessellate as will some higher order polygons.

What famous Greek mathematician came up with an approximate value for pi by circumscribing circles in and around regular polygons?

It was Archimedes.
