On a coordinate plane, quadrilateral A B C D is shown. Point A is at (negative 4, negative 5), point B is at (negative 3, 0), point C is at (0, 2), and point D is at (5, 1). Determine whether quadrilateral ABCD with vertices A(–4, –5), B(–3, 0), C(0, 2), and D(5, 1) is a trapezoid. Step 1: Find the slope of AB. The slope of AB is . Step 2: Find the slope of DC. The slope of DC is . Step 3: Find the slope of BC. The slope of BC is . Step 4: Find the slope of AD. The slope AD is . The quadrilateral is a trapezoid because .
