Math Identification

• Properties of Parallelogram

  • opposite sides are always congruent
  • opposite angles are always congruent
  • consecutive angles are always supplementary (sum of 180 degrees)
  • sum of interior angles is 360 degrees
  • diagonals always biset each other
• Two pairs of congruent sides and angles - Parallelogram
• Square

  • all sides are congruent
  • all sides are right angles (90 degrees)
  • diagonals are congruent and always biset each other and perpendicular
• Rectangle

  • 2 pairs of congruent opposite sides
  • all angles are right angles
  • diagonals are congruent and biset each other
• Rhombus

  • all sides are congruent
  • 2 pairs of congruent opposite angles
  • diagonals are congruent and biset each other and perpendicular
• Sum of interior angles of a quadrilateral - 360 degrees
• Measurement of opposite sides - Congruent
• Measurement of opposite angles - Congruent
• Consecutive angle sum - 180 degrees or supplementary
