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
