area The size of a surface; the amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle;the number of square units that covers a closed figure.
surface area The total area of the surface of a three-dimensional object. Example: the ____________________ of a cube is the area of all 6 faces added together; The ______________ of a three-dimensional figure is the sum of the areas of all its faces.
volume The amount of 3-dimensional space an object occupies. Capacity.
decomposing the process of separating numbers into their components (to divide a number into smaller parts). 456 can be decomposed as 456 = 400 + 50 + 6
edge a line segment that joins two vertices (on the boundary or where faces meet); the intersection of faces in a three-dimensional figure.
dimensions A measurement of length in one direction. Examples: width, depth and height; used to describe the size and shape of an object.
net A pattern that you can cut and fold to make a model of a solid shape; two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, it is a flattened three-dimensional figure which can be turned into the soli
vertex; plural = vertices A point where two or more straight lines meet. A corner.In a three-dimensional object, the point where two edges intersect or meet
face Any of the individual flat surfaces of a solid object.
base the bottom of a plane or a solid.
height Vertical distance from the top of an object or figure to its base
trapezoid a polygon has 2 sides that are parallel lines.; a quadrilateral with only one pair of parallel sides; (4-sided flat shape with straight sides that has a pair of opposite sides parallel.)
isosceles triangle A triangle with two equal sides The angles opposite the equal sides are also equal.
right triangle A triangle that has a right angle (90°)
quadrilateral A flat shape with four straight sides; a four-sided polygon.
rectangle a quadrilateral with four right angles.
square 0A 4-sided flat shape with straight sides where all sides have equal length, and every interior angle is a right angle (90°) It is a Quadrilateral and a Regular Polygon
parallelogram A 4-sided flat shape with straight sides where opposite sides are parallel. Also, opposite sides are equal in length, and opposite angles are equal
rhombus (plural = rhombi) A 4-sided flat shape with straight sides where all sides have equal length. Also opposite sides are parallel and opposite angles are equal. It is a type of parallelogram.
kite A 4-sided flat shape (quadrilateral) with straight sides that:has two pairs of sides, each pair is made of two adjacent sides (they meet) that are equal in length (congruent). Also, the angles are equal where the pairs meet; has one line of symmetry.
right rectangular prism A solid (3-dimensional) object which has six faces that are rectangles. It has the same cross-section along a length, which makes it a prism. It is also a "cuboid".
diagonal a line segment connecting two non-adjacent vertices of a polygon. A straight line inside a shape that goes from one corner to another (but not an edge).
