DaVinci used lots of linear perspective in his artwork including The Last Supper. Without the math and geometry he would not have been able to create such realistic and mesmerizing artwork. Golden Ratio is a non square rectangle that have a line drawn within it parallel to the short side that portions it into a square and a smaller rectangle. The Renaissance were exploring and learning everything but the art still focused on their traditional. Another Renaissance art is the Mona Lisa, DaVinci used geometry to make the figure proportionate because it was helped by the triangles to even symmetrical the eyes and mouth together. The golden triangle draws the eye up. It is to draw an attention to the Mona Lisa’s face.
