|Horizontally, the face is divided by 8 lines which creatd 6 special zones.||1. Divide face into 2 equal 1/2 by drawing a line at the: 1. vertex, top, of the cranium 2. The line of the eye closure, 3. Base of the chin|
2. Divide the face into 3 equal part by drawing lines through the: 1. hairline 2. eyebrows 3. base of the nose 4. base of the chin
3. Divide the are between the base of the nose and the base of the chin into 3 equal part by drawing lines through: 1. base of the nose 2. line of the lip closure 3. top of the chin 4. base of the chin.
|Vertical lines are used to determine the width of head feature by using the width of the eye as a standard of measurement.||1. Draw a line down from the medial corner of each eye. This line will extend to the corner of the wing of the nose. |
2. Extend a line down from the lateral corner of each eye. This line will extend to the sides of the face.
3. Extend a line down from the middle of the eye. This line will extend to the corner of the mouth.
|Three||The face is ___ nose long.|
|Equal||The length of the nose is ___ to the length of the ear.|
|Equal||The width of the nose at the wings is ___ to the width of an eye.|
|5 eyes wide||The face is ___ eyes wide from zygomatic arch to zygomatic arch.|
|one eye||The distance between the eyes to the width of ___.|
