Geometry makes a fashion statement

Geometry and fashion design intersect in this STEM Behind Cool Careers activity that explores an elementary geometric shape – the circle – with one piece all designers must master – the circle skirt.

Style by STEM explores the geometric principles – including the Pythagorean Theorem – designers use to make the skirt and challenges students to observe, investigate and reason with math to:

• Develop the equation for a circle
• Write equations of circles given a radius and center
• Solve equations of circles for y in terms of x

John Urschel, the former professional football player who is also a published mathematician, visited fashion designer Mario Alberto Gallegos for a hands-on look at the STEM behind this cool, chic career.
