Question

identify $\angle edc$ by clicking and dragging the small yellow dots to shade the angle.

Explanation:

Step1: Identify the vertex

The angle \( \angle EDC \) has its vertex at point \( D \). So we first locate point \( D \) in the diagram.

Step2: Identify the two sides

The two sides of the angle are \( DE \) and \( DC \). So we find the yellow dots on the segments \( DE \) and \( DC \) (and at point \( D \)) and drag them to shade the region between \( DE \) and \( DC \) with vertex at \( D \).

Answer:

To identify \( \angle EDC \), shade the angle with vertex at \( D \), between the segments \( DE \) and \( DC \) by dragging the yellow dots on \( DE \), \( D \), and \( DC \). (Note: Since this is an interactive task, the actual action is to manipulate the yellow dots on the diagram to highlight the angle at \( D \) between \( DE \) and \( DC \).)
