Area, Surface Area, Volume, Triangles, Angle Pairs

Area of a Rectangle A = lw
Area of a Trapezoid A = ½ h(b1 + b2)
Surface Area of a Cylinder S.A. = 2πr^2 + 2πrh
Surface Area of a Rectangular Prism S.A. = 2wl + 2lh + 2wh
Surface Area of a Triangular Prism S.A. = 2Abasetriangle + Aface1 + Aface2 + Aface3
Perimeter The distance around the outside of a figure.
Area The amount of square units inside of a figure - always units raised to the second power
Surface Area The total area of the surface of a three-dimensional object - always units raised to the second power
Volume The amount of three dimensional space an object occupies - always units raised to the third power
The Sum of the Angles of a Triangle 180 degrees
Triangle Inequality Theorem Any two sides of a triangle added together must be greater than the third side. For example, 3, 4, and 5 could be the sides of a triangle because 3 + 4 > 5, 4 + 5 > 3, and 3 + 5 > 4.
Scalene Triangle No sides are equal
Isosceles Triangle Two sides are equal
Equilateral Triangle All sides are equal
Right Triangle One 90 degree angle
Acute Triangle All angles are less than 90 degrees
Obtuse Triangle One angle greater than 90 degrees
Volume of General Prisms V = Bh; B stands for area of the base, h stands for height of the prism (distance between two bases) *on reference sheet*
Volume of Pyramid V = 1/3Bh; B stands for area of the base, h stands for height of the pyramid *on reference sheet*
