Shapes
volume of a triangular prism= length x width x height / 2
Volume: amount of space occupied by a 3-D objects measured in cubic units
Base: bottom of something
Height: the measurement from top to bottom
distance across from side to side
Volume= length x width x height
angles
obtuse = any angle between 90° and 180°
an angle measuring less than 90°
right angle = an angle measuring 90°
complementary angles= 2 angles whose sum equals 90°
Transformations
Reflection: A mirror view
Translations: Move an item in any direction, without rotating it
Rotations: To turn an object
Dilations: Becoming wider, larger or more open
Area and Perimeter
Perimeter
L + L + W + W =
L x 2 + W x 2=
Area
Triangle: Width x Height/ 2
Trapezoid: (Base + Top) x Height/ 2
Area of square: W x H
Parallelogram: Base x Height
