This type of shape has an irregular edge.

A shape that has an irregular edge has:

NO lines of symmetry and all the sides are not the same.

So look for a shape like that!

The type of shape you are referring to with an irregular edge is called a "freeform shape" or "irregular shape." These shapes do not have straight sides or regular angles like other geometric shapes such as squares or triangles. Freeform shapes can have curved edges, jagged edges, or a combination of both, resulting in a unique and non-uniform outline.

The type of shape you are referring to is called an irregular shape.

To determine if a shape has an irregular edge, you need to look for certain characteristics. Here's how you can identify an irregular shape:

1. Visual Inspection: Start by visually examining the shape. Look for any edges that do not fall into a recognizable geometric pattern, such as straight lines or smooth curves. Irregular shapes tend to have edges that are uneven, jagged, or winding.

2. Counting Sides: Irregular shapes typically have a varying number of sides. Count the number of sides the shape has. If the sides are not equal in length or do not follow a predictable pattern, this suggests an irregular edge.

3. Measuring Angles: Measure the angles formed by the intersecting sides of the shape. If the angles are not consistent and do not conform to standard angles (e.g., 90 degrees for rectangles), this is an indication of irregularity.

4. Comparing to Known Shapes: Compare the shape to familiar geometric shapes like squares, triangles, or circles. If the shape does not resemble these well-known shapes and has an uneven or unpredictable edge, it is likely irregular.

Remember, irregular shapes can vary greatly in their appearance and attributes, so analyzing multiple aspects is essential in determining irregularity.
