True or False - correct answer True A=1/2 only works when it is a - correct answer Right triangles (the base and height must be perpendicular) Equilateral triangle area formula - correct answer (Square root of 3 / 4) Side Squared Pythagorean Theorem - correct answer a²+b²=c² (only works for 90 degree triangels) isosceles right triangle - correct answer 45 45 90 degree triangel Common Triplets - correct answer 3-4-5, 5-12-13, 6-8-10, 7-24-25, 15-20-25, 8-15-17 45 45 90 triangle - correct answer Multiply side length by square root of 2 to find hypotenuse. (Divide to do opposite) 30 60 90 Triangle - correct answer 90 degree side length is double 30 degree and 60 degree angle side length is 30 degree side length multiplied by square root of 3. Integers - correct answer Whole numbers only Can only combine simplify interior of radicals when - correct answer They are multipled or divided, NOT ADDED Converting radians to degrees - correct answer Pie radians = 180 degrees All side ratios on similar triangles are - correct answer = Similar triangles are - correct answer Triangles that can be converted to each other using one constant ratio Similar triangles are triangles that have - correct answer 2 = angels The Three Sides Of a triangle - correct answer The sum of the lengths of any two sides of a triangle must be greater than the length of the third side Formulas for a square - correct answer A=side•side P=4S Formulas for a rectangle - correct answer A=lw P=2(l+w) Formulas for a parallelogram - correct answer A=lh P=2(l+w) Formulas for a trapezoid - correct answer A=average of bases (h) P=sum of sides How to find the sum of all interior angels - correct answer (N-2)(180) Radius of a circle - correct answer The distance between the center of the circle and the edge (1/2d) Diameter of a circle - correct answer The width of the circle (2r) The area of a circle - correct answer A=pie(r)squared Fractional area of a circle - correct answer x=angle A=(x/360)pie(r)squared Circumference formula - correct answer C=2pie(r) Fractional circumference formula - correct answer x=angel C=(x/360)2pie(r) Rectangular solid formulas - correct answer Surface Area= 2lw + 2wh + 2lh Volume= lwh Diagonal (d)= square root of l squared + w squared + h squared Cube formulas - correct answer Surface area = 6s squared Volume= s cubed Diagonal (d)= s(square root of 3) Cylinder equations - correct answer Surface Area= 2(pie r squared) + (2pie r)h Volume= (pie r squared)h What is a diagonal - correct answer The longer line that can fit within a 3D figured Right circular cone formulas - correct answer V= 1/3pie(r squared) • H Surface Area =1/2(2pie r•slant height) + base area Sphere formuals - correct answer V= 4/3 pie(r squared) Surface Area= 4pie(r squared) Right square pyramids formulas - correct answer Volume= 1/3(base area • height) Surface Area= base area+1/2(perimeter•slant length) You can solve for the volume of any figure which has bases that are both perpendicular to the height with this formula - correct answer Area of the base • Height = volume Equation of a line - correct answer y=mx+b M=slope X=variable B=y intercept/starting point Slope formula - correct answer Rise/run OR (y2-y1)/(x2-X1) Parallel lines have - correct answer The same slope Perpendicular lines have - correct answer Opposite slopes m1= -1/m2 (If m1 and m2 are perpendicular lines) Midpoint formula - correct answer (x1+x2)/2, (y1+y2)/2 Distance formula - correct answer d = √[( x₂ - x₁)² + (y₂ - y₁)²] Trigonometry only deals with - correct answer Similar right triangles SOH CAH TOA - correct answer Opposite/hypotenuse , Adjacent/hypotenuse , Opposite/adjacent Sin of one angel is = to - correct answer Cos of the other acute angel in the triangle Equation of a circle - correct answer (x-h)squared + (y-k)squared =r squared h & k represent center of circles x & y represent any point on the line of the circle Formulas for a rhombus - correct answer A=1/2 (diagonal 1) (diagonal 2) P=4S
