Basic Perimiters

Concave 

-Found in front, back, and side 

perimeters. The line forms an arc with 

the curve open at the bottom. (Hint: 

Think of a cave door.)

Convex

-Found in front, back, and side 

perimeters. The line forms an arc, with 

the curve open at the top. 

“V” 

-Found in front and back perimeters. Theline forms a V, which is either strongly 

or slightly angled. The inverted V is the 

reverse form.

Horizontal 

-Found in front, back, and side 

perimeters. The line is parallel to the 

floor.

Asymmetrical 

-Found in front, side, and back 

perimeters. The hair is longer on one 

side than the other.

Forward Diagonal  

-Found in the side perimeters. The hair 

on the side perimeter is shorter at 

the back, getting progressively longer 

toward the front.

Backward Diagonal  

-Found in the side perimeters. The hair 

on the side perimeter is longer at 

the back, getting progressively shorter
