Introducing Angles!

Straight Angle

EXACTLY 180 degrees

Classifying Quadrilaterals

Parallelogram

  • Quadrilateral (4 sides)
  • Opposite SIDES = congruent
  • Opposite ANGLES = congruent
  • Opposite sides = parallel

Rectangle

  • Quadrilateral
  • Opposite sides = PARALLEL
  • ALL 4 angles = right (90 degrees)
  • Opposite sides = CONGRUENT!

Rhombus

  • Quadrilateral
  • Opposite sides = parallel
  • ALL sides are CONGRUENT!
  • Opposite angles = congruent

Trapezoid

  • Quadrilateral
  • EXACTLY one pair of parallel sides

Square

  • Quadrilateral
  • ALL angles = right (90 degrees)
  • Opposite sides = PARALLEL!
  • ALL SIDES are CONGRUENT!!

Types of Triangles

There are 6 types of TRIANGLES! Let me show you.
