| What is Area? | Area is the measure of the surface enclosed within a plane figure. It is calculated by counting the number of square units needed to cover the surface.
🗑
|
||||
| What is the formula(s) for area? | Square: Area = side length × side length
Rectangle: Area = length × width
🗑
|
||||
| What is Perimeter? | Perimeter is the total distance around a plane figure. It is calculated by summing the lengths of all the sides.
🗑
|
||||
| What is the formula(s) for area? | Square: Perimeter = 4 × side length
Rectangle: Perimeter = 2 × (length + width)
🗑
|
||||
| Point | An exact location in a plane or space with no dimensions.
🗑
|
||||
| Lines | A collection of points extending infinitely in both directions with no endpoints.
🗑
|
||||
| Line Segments | A portion of a line with two endpoints and all points between them.
🗑
|
||||
| Rays | A part of a line that starts at a specific endpoint and extends infinitely in one direction.
🗑
|
||||
| Angles | ormed by two rays with a common endpoint called the vertex.
🗑
|
||||
| Vertices | The common endpoint where two rays, line segments, or lines meet to form an angle.
🗑
|
||||
| Intersecting Lines | Lines that cross each other at exactly one point.
🗑
|
||||
| Perpendicular Lines | Lines that intersect at a right angle.
🗑
|
||||
| Parallel Lines | Lines in the same plane that never intersect and are always the same distance apart.
🗑
|
||||
| Quadrilateral | A polygon with four sides.
🗑
|
||||
| Parallelogram | A quadrilateral where both pairs of opposite sides are parallel and congruent.
🗑
|
||||
| Rectangle | A quadrilateral with four right angles, opposite sides that are parallel, and opposite sides that are congruent
🗑
|
||||
| Rhombus | A quadrilateral with four congruent sides, opposite sides are parallel, and opposite angles are congruent.
🗑
|
||||
| Square | A special type of rectangle and rhombus with four congruent sides and four right angles.
🗑
|
||||
| Trapezoid | A quadrilateral with exactly one pair of parallel sides.
🗑
|
||||
| Congruent Figures | Figures that have the same size and shape. Congruent sides have the same length, and congruent angles have the same measure.
🗑
|
||||
| Plane Figure | A closed, two-dimensional shape.
🗑
|
||||
| Solid Figure | A three-dimensional shape with length, width, and height.
🗑
|
||||
| Vertex | The point where three or more edges meet in a solid figure.
🗑
|
||||
| Face | A flat surface of a solid figure.
🗑
|
||||
| Edge | A line segment where two faces of a solid figure intersect.
🗑
|
||||
| Angle | Formed by two rays with a common endpoint called the vertex. Angles are found where lines or line segments intersect.
🗑
|
||||
| Cube | A solid figure with six congruent square faces, all edges are the same length. It has eight vertices and 12 edges.
🗑
|
||||
| Rectangular Prism | A solid figure with six rectangular faces. It has eight vertices and 12 edges. A cube is a special case of a rectangular prism.
🗑
|
||||
| Sphere | A solid figure where all points are the same distance from the center.
🗑
|
||||
| Square Pyramid | A solid figure with a square base and four triangular faces that meet at a common vertex. It has five vertices and eight edges.
🗑
