Topic 8 Surface & Volume
Adjacent Angles: angles that share a ray
Area: the number of square units (or fraction thereof) that cover a shape
Base: a side of a polygon (not necessarily the "bottom") used for reference to other sides
Circumference: the perimeter of a circle
Complementary Angles: a pair of angles that total a right angle
Composite Figure: a shape made of other shapes "stuck" together
Cross Section: the intersection of a plane and a space (3-D) shape
Diameter: the longest length of a chord of a circle, or one of those chords. The distance from the circle to the circle, through the center.
Height: the length from one base of a right rectangular prism to the other.
Parallel: describes coplanar, non-intersecting lines
Parallelogram: a quadrilateral with two pairs of parallel sides
Perpendicular: describes lines that meet at all equal angles
Quadrilateral: a polygon with exactly four sides
Radius: a segment from the circle to its center, or the length of that segment
Rectangle: a quadrilateral with all equal angles
Rhombus: a quadrilateral with all equal sides
Scale Drawing: a figure whose lengths are proportional to the original, and whose angles are the same.
Square: a rectangle rhombus
Supplementary Angles: a pair of angles that total a straight angle
Surface Area: the total area of all surfaces of the figure
Trapezoid: a quadrilateral with exactly one pair of parallel sides
Triangle: a polygon with exactly three sides
Unique Triangle: a description of a triangle that creates only congruent triangles
Vertical Angles: non-adjacent angles formed by a pair of intersecting lines
Volume: the number of cubic units (or fraction thereof) that fill a shape
