AI Drawing Prompt Reference

Draw a graphic showing various angles like acute, right, obtuse, and straight angles found in daily life. Use sliders to adjust angles and color-code them. Start by drawing lines representing objects, then measure and label each angle type. Finally, draw a polygon around a central point to mimic a simple telescope, enhancing the visual effect.
