Which polygons have all angles smaller than a right angle?
Remember a right triangle has one 90 degree or right angle, an acute triangle has all angles less than 90 degrees, or less than a right angle, and an obtuse triangle has one angle greater than 90 degrees or greater than a right angle. Now lets learn about polygons. A polygon is a closed figure with straight edges.
What degrees is a hexagon?
A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.

How do you know if a polygon is concave or convex?
Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
What type of polygon must have a diagonal such that at least part of the diagonal falls in the exterior of the polygon?
Properties of a Concave Polygon
Some of the diagonals of a concave polygon will lie outside the polygon. In the figure on the right, the diagonal at the top of the polygon is outside the polygon’s interior space.
What is the polygon rule?
The sides must be straight. Polygons may have any number of sides. A polygon. A shape with curved sides is not a polygon. A shape that is not fully closed is not a polygon.
How do I find the exterior angle of a polygon?
Exterior Angles of a Regular Polygon with n sides: Exterior angle = 360°/n.
How many angles does a trapezium have?
A trapezium is a closed shape or a polygon, that has four sides, four corners/vertices and four angles.
Which of the following polygons has no diagonal?
Answer. A triangle has no diagonals.
Do all polygons interior angles add up to 360?
The common property for all the above four-sided shapes is the sum of interior angles is always equal to 360 degrees. For a regular quadrilateral such as square, each interior angle will be equal to: 360/4 = 90 degrees.
Which of the following figure is not a polygon?
A circle is not a polygon as it does not have straight sides.
Are polygons that have non congruent sides?
Any polygon that does not have all congruent sides is an irregular polygon. Irregular polygons can still be pentagons, hexagons and nonagons, but they do not have congruent angles or equal sides. Here are some examples of irregular polygons.
Which can be considered as the diagonal of a polygon?
In a polygon, the diagonal is the line segment that joins two non-adjacent vertices. An interesting fact about the diagonals of a polygon is that in concave polygons, at least one diagonal is actually outside the polygon.
Which figure is a polygon?
A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.
Are you able to classify polygons by their sides and angles?
Classifying Polygons. A polygon is any closed planar figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.
What makes a polygon concave?
A Concave polygon is a polygon that has at least one interior angle greater than 180 degrees. It must have at least four sides.
How many vertices are in a polygon?
A polygon is a closed shape figure that has a minimum of three sides and three vertices. The term ‘poly’ means ‘many’ and ‘gon’ means ‘angle’. Thus, polygons have many angles.
What polygon has all congruent sides and angles?

What is a 99 sided shape called?
What is a 99 sided shape called? In geometry, an enneacontagon or enenecontagon or 90-gon is a ninety-sided polygon. Thus, the 99 sided shape is called nonacontakainonagon or enneacontanonagon. Here, enneaconta is the prefix for the number of sides numbered from 90 to 99.
What is a nonagon shape?
A nine-sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners, or vertices. The word “nonagon” comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.
How many sides has a octagon?
How is a polygon shape?
In geometry, a polygon can be defined as a flat or plane, two-dimensional closed shape with straight sides. It does not have curved sides.
What are the vertices angles and sides of the polygon?
Vertex – point where two sides meet. Two or more of these points are called vertices. Diagonal – a line connecting two vertices that isn’t a side. Interior Angle – Angle formed by two adjacent sides inside the polygon.
Is the polygon convex or concave regular or not regular?
To be a polygon, the shape must be flat, close in a space, and be made using only straight sides. Polygons with congruent sides and angles are regular; all others are irregular. Polygons with all interior angles less than 180° are convex; if a polygon has at least one interior angle greater than 180°, it is concave.
How do you know if a polygon is convex?
