Math Revew Chapter 5 Flashcards
An exact location in space. It is represented by a dot and has no length, width, or depth.
Point
It is a length made up of points that extend infinitely in both directions
Line
Is a portion of a line having two endpoints
Line segment
Is a portion of a line having one endpoint and extending infinitely in one direction from the endpoint
Ray
It is formed by two rays that share a common endpoint called Vertex
Angle
Are two lines that cross at a point
Intersecting lines
Are lines that never intersect
Parallel lines
Are intersecting lines that form four right angles
Perpendicular lines
Figures that consist of curved lines or straight lines that lie on a flat surface
Plane figures
Shapes like triangles and circles that begin and end at the same point
Closed figures
When a closed figure is made, only straight lines and no curves
Polygon
Polygon with 3 sides
Triangle
Polygon with 4 sides
quadrilateral
Polygon with 5 sides
Pentagon
Polygon with 6 sides
hexagon
Polygon with 7 sides
heptagon
Polygon with 8 sides
Octagon
Polygon with 9 sides
Nonagon
Polygon with 10 sides
Decagon
Any four sided polygon
quadrilateral
Is any quadrilateral that has only one set of opposite sides parallel
Trapezoid
Any quadrilateral that has both sets of opposite sides equal
Parallelogram
Any parallelogram that has all sides equal
rhombus
Any parallelogram that has four right angles
Rectangle
Any rectangle that has all sides equal
Square
Polygon with all sides equal
Equilateral Polygon
Polygon with all angles equal
Equiangular Polygon
Polygon with all sides equal and all angles equal
Regular Polygon
Shapes that have no type of symmetry at all are said to be
Asymmetrical
Two congruent halves that are mirror images
Line Symmetry
Rotated some angle less than full rotation, it is identical to the original.
Rotational Symmetry
Polygons that have the exact same shape and size are
Congruent Polygon
The parts of these polygons that are in a matching position
Corresponding
Polygon that have the same shape but have different sizes
Similar Polygons
Formula perimeter of rectangle
P = 2l + 2w
Formula perimeter of squares
P = 4s
Formula perimeter of General Polygons
P = the sum of the sides
Formula perimeter of Equilateral Polygons
P = (number of sides)(side length
Angles that have a common side between them and share a common vertex
Adjacent angles
Opposite pairs of angles that are equal and have two lines that intersect
Vertical angles
Two angles whose sum is 90
Complementary angles
Are two angles whose sum is 180
Supplementary angles
Angles between the parallel lines, on opposite sides of the transversal
Alternate Interior Angles
Angles outside the parallel lines on opposite sides of the transversal
Alternate Exterior Angles
Angles on the same side of the parallel lines, along the same side of the transversal
Corresponding Angles
Triangle whose angles are less than 90
Acute
Triangle with one angle more than 180
