  5. Describe Sides and Angles Describe the congruent sides in the quadrilateral. Then state whether any sides appear to be parallel or perpendicular. Answer: Opposite sides are congruent and parallel. No sides are perpendicular. Example 1

  6. A B C D Describe the congruent sides in the quadrilateral. Then state whether any sides appear to be parallel or perpendicular. • Opposite sides are parallel and no sides are perpendicular. • Opposite sides are perpendicular but not parallel. • No sides are perpendicular or parallel. • Opposite sides are parallel and adjacent sides are perpendicular. Example 1

  7. Describe Sides and Angles The design is made up of repeating quadrilaterals. Find the number of acute and obtuse angles. Answer: Each quadrilateral has two acute angles and two obtuse angles. Example 2

  8. A B C D The design is made up of repeating quadrilaterals. Find the number of acute angles in each quadrilateral. • 1 • 2 • 3 • none Example 2
