Polygon Property Math
Other important polygon properties to be familiar with include trapezoid properties rhombus and rectangle and square properties.
Polygon property math. You will find the following formulas and properties useful when answering questions involving triangle inequalities right triangles relationships between the angles and sides of triangles and interior and exterior angles of polygons. Sum of the interior angles of a polygon n 2 x 180 the number of diagonals in a polygon 1 2 n n 3 the number of triangles when you draw all the diagonals from one vertex in a polygon n 2 polygon parts. The triangle is the most basic polygon. A concave polygon is defined as a polygon if any internal angle is greater than 180.
Sum of the exterior angles of a polygon. The number of diagonals in a polygon with n sides n n 3 2. The properties of polygons are based on its sides and angles. All triangles the sum.
A polygon is any 2 dimensional shape formed with straight lines. Triangles quadrilaterals pentagons and hexagons are all examples of polygons. Math geometry all content shapes angles with polygons.

A polygon is a geometric figure that has at least three sides. Find the sum of interior angles of different polygons. The number of triangles formed by joining the diagonals from one corner of a polygon n 2. The sum of all the interior angles of an n sided polygon is n 2 180.
To get the area of the whole polygon just add up the areas of all the little triangles n of them. How to identify a kite and its special properties. Area of one triangle base height 2 side apothem 2. 5 votes see 13 more replies.
Area of polygon perimeter apothem 2. And since the perimeter is all the sides n side we get. The name tells you how many sides the shape has. A polygon is made of any three straight sides with the lines all connected to each other as well as not overlapping and meeting at the ends of the lines.
Angles of a polygon. Kite properties include 1 two pairs of consecutive congruent sides 2 congruent non vertex angles and 3 perpendicular diagonals. Any other polygon is an irregular polygon which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons a polygon by definition is made up of straight lines.
Sum of interior angles of a polygon. A regular polygon has equal length sides with equal angles between each side.
