  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. 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 CONNECTIONS

  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
