📚 Quick Study Guide

    📐 A trapezoid is a quadrilateral with at least one pair of parallel sides. 📏 These parallel sides are called bases, and the non-parallel sides are called legs. ➕ The area of a trapezoid is calculated as $A = \frac{1}{2}(b_1 + b_2)h$, where $b_1$ and $b_2$ are the lengths of the bases and $h$ is the height (the perpendicular distance between the bases). 💡Isosceles trapezoids have legs of equal length and base angles that are equal. 🖼️ Many real-world objects approximate trapezoids but may not be perfect mathematical trapezoids.
