To construct a triangle similar to given $\Delta ABC$ with its sides $\large\frac{7}{5}$ of the corresponding side of $\Delta ABC$ draw a ray $BX$ such that $\angle CBX$ is an acute angle and $X$ is on the opposite side of $A$ with respect to $BC$. Then, locate points $X_1,X_2,X_3…$ at equal distances on $BX$. The points to be joined in the next step are
