AI Drawing Prompt Reference

Draw a geometric figure with two intersecting lines forming angles. Start by drawing two line segments and their intersection point, then connect these points to form a quadrilateral. Locate a point inside the quadrilateral and draw two line segments from it. Measure and label the angles formed. Finally, draw a ray from one vertex of the quadrilateral that intersects one of the line segments, creating new angles.
