  • Decagon - Wikipedia
    In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, "ten angles") is a ten-sided polygon or 10-gon [1] The total sum of the interior angles of a simple decagon is 1440° A regular decagon has all sides of equal length and each internal angle will always be equal to 144° [1]
  • Decagon Explored – Definition, Properties, and Examples
    Decagons, with their intriguing shape and symmetrical properties, have captivated mathematicians, artists, and architects for centuries The Greek terms “deka,” which means “ten,” and “gonia,” which means “angle,” a Decagon is a polygon with ten sides and ten angles

    • Decagons are a type of polygon that has 10 sides, 10 vertices, and 10 angles • There are several different types of decagons, including regular, irregular, simple, and complex • Students learn mathematical formulas to calculate the area, perimeter, and angles of a decagon What is a decagon?
  • What is a Decagon? Definition, Shape, Sides, Formula, Examples
    In geometry, a polygon having ten sides or a ten-sided polygon is called a decagon or ten-gon It also has ten vertices and ten angles In the above image, there are 10 sides: AB, BC, CD, DE, EF, FG, GH, HI, IJ, and AJ There are 10 angles Decagon interior angles: ∠ ABC, ∠ BCD, ∠ CDE, ∠ DEF, ∠ EFG, ∠ FGH, ∠ GHI, ∠ HIJ, ∠ IJA, and ∠ JAB
  • Decagonal Numbers - GeeksforGeeks
    A decagonal number is a figurate number that extends the concept of triangular and square numbers to the decagon (a ten-sided polygon) The nth decagonal numbers counts the number of dots in a pattern of n nested decagons, all sharing a common corner, where the ith decagon in the pattern has sides m
