The world is made up of lines -- many of which intersect to form angles. From the shape of our chairs to the architecture of the homes we live in, angles are everywhere.
For this week's Mashable Photo Challenge, we asked you to think about angles.
Readers captured all kinds of intersecting lines and sent in pictures of support cables, buildings and the spokes of a ferris wheel. But not all angles are so literal. A photo taken from an unusual vantage point captures the world from an angle not commonly seen.
You expanded on that idea and sent us all kinds of interesting angled shots from iconic structures, including the St. Louis arch and the Brooklyn Bridge. There was even a Star Wars reference (well done there). These photos convey angle by showing an uncommon perspective.
We selected 20 of the most inspired submissions that show off the various ways you interpreted this week's theme.
