AI Drawing Prompt Reference

Draw five right-angled triangles inside a pentagon, estimating their side lengths and angles. The triangles are nested within the pentagon, sharing some sides with it. Start by drawing the pentagon, then construct five right-angled triangles inside it one by one, marking the angles at each triangle's non-right corners. Finally, measure and label the side lengths and angles of all triangles to illustrate geometric construction, trigonometric applications, and introductory calculus concepts.
