By the end of the sixties, Àngels Ribé had abandoned formal sculpture for actions using the body, which were intended as experiences embracing nature and perception. Although in her first actions experimented with minimal elements such as glass or nylon thread in natural contexts, she soon began to incorporate her own body, as in the 3 punts series. As the title indicates, these works offer different variations on the triangle, the simplest figure to join three points and one of the basic measures of the world for investigating the geometric condition of space.
