Arrange the four angles from smallest to largest by comparing how wide each angle opens.<br><br>
&bull; Look at angles a, b, c, and d in the figure.<br>
&bull; Order them from narrowest opening (smallest angle) to widest opening (largest angle).<br>
&bull; None of the given sequences (a, b, c, d), (b, a, d, c), or (c, a, d, b) matches the correct order from the figure.<br>
&bull; The correct answer is "None of the above."<br><br>
Final Answer: None of the above
