Question
Construct $\angle \mathrm{ABC}=120^{\circ}$, where $\mathrm{AB}=\mathrm{BC}=5 \mathrm{~cm}$. Mark two points $\mathrm{D}, \mathrm{E}$ which satisfy both the following conditions (a) equidistant from BA and BC (b) at a distance of 5 cm from B . Point E is on the side of reflex $\angle \mathrm{ABC}$. Join $\mathrm{AE}, \mathrm{EC}$, $C D$ and $A D$. Describe the figures (i) $A E C D$ (ii) $A B D$ (iii) $A B E$.
