Transcript

  • 1. MATHEMATICS SQUARES SQUARE ROOTS
  • 2. TODAY’S MATH PREVIEW
    • AREA OF SQUARES
    • AREA OF RECTANGLES
    • AREA OF TRIANGLES
    • CONNECTIONS
      • Exponents
      • Pythagorean Theorem
  • 3. MATH RELATIONS
    • Square Roots
    • Scientific Calculators
  • 4. Area of Squares
    • Area formula:
    • A=s² (A=area & s=side)
    • S²means sxs
  • 5. Area of Rectangles
    • Area formula:
    • A = l x w
    • L = length
    • W = width
  • 6. Area of Triangles
      • Area formula:
      • A = ½ bh
      • B = base
      • H = height or altitude
  • 7. Types of Triangles
    • Acute: triangles with angles less than 90º
    • Obtuse: triangles with one angle greater than 90º but less than 180º
    • Right: triangles with one angle equaling 90º
  • 8. CONNECTIONS
    • Exponents:
    • 7² = 7 x 7
    • 7² where 7 is the BASE and ² is the exponent.
    • Pythagorean Theorem:
    • A²+B²=C²
    • The square root of A & B are legs and the square root of C is the hypotenuse of the right triangle
  • 9. Square Roots
    • One of the two equal factors of a number.
    • A square root of 144 is 12 since 12 squared = 144.
  • 10. Scientific Calculator
    • Enter square root symbol before entering the number
    • Press enter or equal
