Book I Proposition 4 | |
Therefore, letting two triangles have two sides (legs?) of one equal to two sides of the other respectively and the angle contained by the sides of the one equal to the angle contained by the sides of the other, then also the base of the one will equal to the base of the other and the one triangle will be equal to the other and the remaining angles of the one will be equal to the remaining angles of the other respectively, being those which the equal sides subtend. This being the very thing it was necessary to show. |
