Play around with the vertices of the quadrilateral. Pay attention to the angle measures in the quadrilateral.
What will the sum of interior angles in a quadrilateral always be equal to?
Consider this quadrilateral. Can you explain WHY a quadrilateral will always have an angle sum of 360 degrees?
Consider the Trapezoid below. Play with the vertices.
What do you think might be some properties of a trapezoid?
Consider the Isosceles Trapezoid below.
What did you notice is different in an isosceles trapezoid than just a regular trapezoid? What generalizations can you make?
