Which polygon has odd number of sides?

If a regular polygon has an odd number of sides, then it has as many lines of symmetry as it has sides. In each case, the line of symmetry will pass through a vertex and the midpoint of the side opposite this vertex. Other, nonregular polygons may or may not have any line of symmetry.

How many corners do polygons have?

So, this polygon has an equal number of sides and vertices. Quadrilaterals have four sides and four corners. The number of sides and vertices are equal. Pentagons are polygons with five sides and five corners.

What shapes have right angles?

Squares, rectangles, and right triangles all have right angles.

Does a concave polygon have an odd number of sides?

Give a co counterexample for any false conjecture polygon Conjecture: It can be regular Given: a concave or irregular False a concave polygon has an odd number of sides. False; all concave polygons are regular False; to be concave the angles cannot be congruent True.

What’s a one sided shape called?

List of n-gons by Greek numerical prefixes

Sides	Names
1	henagon	monogon
2	digon	bigon
3	trigon	triangle
4	tetragon	quadrilateral

What is a 5 sided shape?

pentagon
A pentagon is a five-sided polygon. A regular pentagon has 5 equal edges and 5 equal angles.

What shape has no right angles?

rhombus
A rhombus is a quadrilateral with 4 equal sides. A shape with four sides of equal length. The shape has two sets of parallel sides and does not have right angles. A shape with four sides of equal length.

Which shape does not have right angles?

Other Types of Quadrilaterals Different from a rectangle, a parallelogram does not have to have four right angles. A rhombus is a quadrilateral where all four sides are equal in length. Different from a square, a rhombus does not have to have four right angles.

What is an irregular 5 sided shape called?

For instance, a shape with five sides of varying lengths and interior angles which measure differently is still a pentagon. However, they’ll often add the word ‘irregular’ in front of it to indicate that the shape’s sides and angles aren’t equal. So, they’ll call it an irregular pentagon.

What do you call a polygon whose sides are not equal?

Definition: Any polygon that is not a regular polygon. A polygon whose sides are not all the same length or whose interior angles do not all have the same measure.
