Regular shapes are __ ; irregular shapes are __ square and round organic and geometric geometric and organic organic and biomorphic

## Step 1<br />The problem is asking us to identify the correct pair of terms that represent regular and irregular shapes. <br /><br />## Step 2<br />Regular shapes are those that have a consistent and predictable form. They are often associated with geometric shapes, which are defined by their mathematical properties. Examples of regular shapes include squares, circles, and triangles.<br /><br />## Step 3<br />On the other hand, irregular shapes do not have a consistent form. They are often associated with organic shapes, which are defined by their natural, free-form appearance. Examples of irregular shapes include the shapes of leaves, animals, and other natural objects.<br /><br />## Step 4<br />Given the above definitions, the correct pair of terms that represent regular and irregular shapes is "geometric and organic".
