Answer: A 10 sided shape is called a decagon
A 10 sided shape is a geometric figure with ten straight sides and ten angles. In mathematics, shapes are often named according to the number of sides they possess. Understanding these names helps in geometry, especially when identifying, classifying, or working with polygons.
Methods
Math Tutor Explanation Using Polygon Naming Conventions
Polygons are named by combining Greek number prefixes with the suffix '-gon', which means angle.
Step 1: Step 1: Identify how many sides the shape has, which is 10
Step 2: Step 2: Use the Greek prefix for ten, which is 'deca'
Math Tutor Explanation Using Examples of Polygons
Recognizing patterns in polygon names helps to quickly identify shapes based on the number of sides.
Step 1: Step 1: Recall familiar shapes like triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), etc
Step 2: Step 2: Follow the sequence up to 10 sides to find that a decagon is the correct term
