Area : The amount of unit squares that is needed to cover a 2-dimensional shape.
Base : When using the height of a triangle or parallelogram (for example in an area calculation), base refers to the side of the triangle or parallelogram that the height starts out at. In a logarithm $\log_{b}x$ or power $b^x$ base refers to the number $b.$
Centimeter : A centimeter ($cm$) is $\frac{1}{100}$ of a meter.
Height : In a triangle a height (or altitude) is the shortest line segment that connects a side to its opposing corner. A height of a triangle is perpendicular to the side is started at. The three heights of a triangle intersect in a point, the so called orthocenter of the triangle. In a parallelogram the height is the shortest distance between two opposing sides. In a pyramid the height is the shortest distance between the base area and the corner of the pyramid that is not part of the base area. In a prism the height is the shortest distance between the two base faces.
Parallelogram : A parallelogram is a quadrilateral with 2 pairs of parallel sides. Rectangles, rhombuses and squares are special kinds of parallelograms.
Square centimeter : Square centimeter or $cm^2$ is a unit of measurement for measuring area. 1 square centimeter is the area of a square with side length 1 $cm,$ so 10,000 $cm^2$ are one $m^2.$
What is the area in square cm of a parallelogram that has a base of 1 cm and a height of 3 cm?
Alternate exterior angle : When two parallel lines are crossed by a third line, alternate exterior angles are a pair of angles that are not between the two parallel lines and are on opposites sides of the crossing line. Alternate exterior angles are equal.
Alternate interior angle : When two parallel lines are crossed by a third line, alternate interior angles are a pair of angles that are between the two parallel lines and are on opposites sides of the crossing line. Alternate interior angles are equal.
Angle : If two line segments (or rays) both start at a common point the opening between the two line segments is called an angle. The common point is called vertex of the angle. The size of an angle is measured in degrees.
Line : A line AB is a one-dimensional shape that includes the points A and B, all the points on the line segment in between A and B and all the points of the straight extension of the line segment beyond A and B. A line does not have an endpoint.
Opposite angle : In a quadrilateral an opposite angle is the angle at the opposite corner of the corner where the angle is located.
Parallel : Two lines in a two-dimensional plane are called parallel if they never cross.
Which statements are true about the angles $a, b, c, d, e, f, g$ and $h$ at the crossings of the line EF with the parallel lines AB and CD in the picture above?
Cube : A cube is a three-dimensional shape with 6 faces that are all squares. A cube has 8 corners and 12 edges.
Edge : An edge of a shape is a line segment between two corners of that shape.
Length : Length is the attribute of a one-dimensional shape that can be measured with a measuring tape.
Surface area : The surface area of a three-dimensional shape is the area of the surface of the three-dimensional shape. For example the surface area of a cube with edge length 1 $cm$ is 6 $cm^2.$
What is the surface area in $cm^2$ of a cube with edge length 7 cm?
