Question | Answer |
---|---|
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 |
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* |
