MATH RELATIONS Square Roots Scientific Calculators

Area of Squares l Area formula: l A=s² (A=area & s=side) l S²means sxs

Area of Rectangles l Area formula: l A = l x w l L = length l W = width

Area of Triangles Area formula: A = ½ bh B = base H = height or altitude

Types of Triangles l Acute: triangles with angles less than 90º l Obtuse: triangles with one angle greater than 90º but less than 180º l Right: triangles with one angle equaling 90º

CONNECTIONS l Exponents: l 7² = 7 x 7 l 7² where 7 is the BASE and ² is the exponent. l Pythagorean Theorem: l A²+B²=C² l The square root of A & B are legs and the square root of C is the hypotenuse of the right triangle

Square Roots One of the two equal factors of a number. A square root of 144 is 12 since 12 squared = 144.
