Praxis II Elementary Education Multiple Subjects 5001 (2023/2024) Already Passed Distributive Property Distribute and factor a(b +c) = b(a + c.) Associative Property Regrouping (a + b) + c= a + (b + c) Good for combining like terms Composite Number A number that can be divided evenly. More than one factor. Prime Number Only has multiples of 1 and itself. Commutative Property of Addition Move things around a + b= b+ a Identity property (Multiply and add) 9 + 0= 9 5 x 1 = 5 Complementary Angles Two angles that add up to 90 degrees Concurrent Lines A set of lines/curves that intersect at a single point Adjacent Angles Two angles are adjacent if they share a side and vertex Atoms basic building blocks of matter paleontology branch of science concerned with fossils, animals, and plants atmosphere -made up of 5 basic layers -thick to thin -weather occurs in troposphere stratosphere absorbs rays Neptune -8th planet -Third largest -12 moons -Great Dark Spot -Very cold w/ huge winds Saturn -6th planet -2nd largest -61 moons -core made of rock and ice -has rings Jupiter -5th planet -Largest (gas giant) -63 moons -Great Red Spot Earth -LIFE -3rd planet -71% salt water -rocky -1 moon -78% nitrogen, 21% oxygen, 1% argon biological classification KINGDOM PHYLUM CLASS ORDER FAMILY GENUS SPECIES (kind people can order fries w/ gravy sauce) Triangle 3 sides polygon Quadralateral 4 sides Pentagon 5 sides Hexagon 6 sodes Heptagon 7 sides Octagon 8 sides Nanogon 9 sides Decagon 10 sides Dodegon 12 sides 5 common quadrilaterals Rhombus, square, rectangle, trapezoid, and parallelogram Square 4 equal sides, 4 equal angles Rectangle Parallelogram with 4 equal angles and 2 sets of equal sides Trapezoid One pair of parallel sides Rhombus 4 equal sides Parallelogram 2 pair of parallel sides, 2 equal sides Opposite sides congruent Triangles 3 sides Acute Less than 90 Obtuse More than 90 Right 90 degrees Equalateral All equal sides, also acute Isosceles 2 equal sides Scalene No equal sides, 3 different angles, largest angle opposite longest side, smallest angle-opposite shortest angle Pythagorean Theory a2 + b2 = c2 C always the hypotenuse and a and b are the remaining sides Only right triangles Reflex angle Degree greater than 180 but less than 360 Full angle Degree of exactly 360 Straight angle 180 Semicircle Complementary 2 angles whose sum = exactly 90 Usually right triangles Supplementary 2 angles whose sum = 180 2 intersecting lines always form 2 pairs of supplementary angles Adjacent 2 angles with same vertex are adjacent Formula for area of triangle 1/2 (b . h) Formula for area of trapezoid 1/2h (b1 + b2) Area of circle Pie r2 Perimeter of circle 2 pie r Diameter 2r Sum of angles of polygons Increases by 180 per additional side/angle. Triangle 180 Square 360 Pentagon 540 etc. Mass How much substance in an object Weight Measure of earth's gravity on an object Volume Measure of occupied soace Density Measure of mass per volume Specific gravity Measure of density compared to water 4 states of matter Solid, liquid, gas, and plasma Solid Definite volume and density. Slow molecules, resistant to flow Liquids Definite volume and density. Flows readily and doesn't expand to fit containers like gas. Fast molecules Gas Expands to fill container. Fastest molecule. Atomic number Number of protons and neutrons in nucleus Periodic table Chemical elements only. No mixtures or compounds. Rows have same number of election shells. Columns have same electron configuration.
