His reasoning behind this is that the figure cannot help having a certain nature, form, or essence which is unalterable and is in fact eternal. As well, He argues that it is evident he could not have simply invented the figure, that evidence being the properties of the triangle. Firstly, a triangle consists of three angles which are equal to two right angles, and secondly that the greatest angle is opposite from the longest side. Ultimately, Descartes argues that this evidence shows that it cannot be said that he has imagined or invented the triangle, although it exists as an idea in his mind. In relation to Descartes values, due to the fact he clearly and distinctly perceives all properties of the triangle, than he argues it must in fact have all the properties
