The task is tricky. Because it has four right angles, a square is also a rectangle. Second property of a parallelogram – The opposite sides are equal As an example, this proof has been set out in full, with the congruence test fully developed. Proving Parallelograms – Lesson & Examples (Video) 26 min. Thus all parallelograms have all the properties listed above, and conversely, if just one of these statements is true in a simple quadrilateral, then it is a parallelogram. It requires students to apply all properties of special parallelograms and to think about proofs before actually writing them. BetterLesson reimagines professional learning by personalizing support for educators to support student-centered learning.
