• # question_answer How many obtuse angles are there in the figure given below? A) Two                     B)       Three C) Four                              D) Five E) None of these

Explanation: Option (b) is correct. Clearly, $\angle \text{ABC}$ and $\angle \text{DCB}$ are right angles but $\angle \text{BAE, }\angle \text{AED}$ and $\angle \text{CDE}$ are of more than $90{}^\circ$ but less than $180{}^\circ$ (obtuse angles).
