    • Jason's Guide to Geometry
        • Lines
        • angles
        • Triangles
        • Quadrilaterals
        • circles
    • LINES
    • lines
      • Keeps going forever in both ways
    • Points
      • A point is a precise location in a space. It is labeled with a letter.
    • plane
      • A flat surface that extends without end, in all directions
    • Line segments
      • Any lined that can be measured
    • Rays
      • Starts and only goes one way
    • Intersecting lines
      • Cross at a point
    • Perpendicular lines
      • Intersect at right angles
    • parallel
      • Lines in a plane that are always the same distance
    • Skewer lines
      • Line that aren't in the same plane
    • ANGLES
    • Acute
      • An acute angle is less than 90 degrees
    • obtuse
      • An angle that is more than 90 degrees
    • Right Angle
      • A 90 degree angle
    • Vertex/vertices
      • A vertex is a middle point of a three point angle
    • Complementary
      • To angles that make a 90 degree angle
    • Supplementary
      • Two angles that add up to the sum of 180
    • Adjacent
      • Angles that are side by side and have common vertex and ray.
    • TRIANGLES
    • Right triangle
      • A triangle with one right angle
    • Obtuse triangle
      • A triangle with one angle grater that 90 degrees
    • Acute triangle
      • A triangle with all angles less than 90 degrees
    • Scalene triangle
      • A triangle with no congruent sides
    • Isosceles triangle
      • A triangle with exactly two congruent sides
    • Equilateral triangle
      • A triangle with three congruent sides
    • Sum of a internal angle
      • The sum of all the angles inside a shape
      • Triangle=180
      • square=360
    • perimeter
      • The distance around a figure
    • Area of triangle
      • The space inside a triangle
    • QUADRILATERALS
    • Quadrilateral
      • A quadrilateral is a polygon with four sides and four angles.
    • trapezoid
      • A quadrilateral with exactly two parallel sides.
    • Parallelogram
      • A quadrilateral that has opposite sides that are parallel and congruent
    • Rectangle
      • A parallelogram with four right angles
    • rhombus
      • A rectangle with four congruent sides
    • Square
      • A rectangle with four congruent sides
    • Are of a Rectangle
      • The area of a rectangle is the length time width or how many blocks total can fit in it
    • Area of a square
      • How long the width is x the length or how many blocks can fit in there
    • Area of a parallelogram
      • The base times height
    • Area of a trapazoid
      • The area of this is the space inside the shape
    • Perimeter of a rectangle
      • To find the perimeter of a rectangle you add all of the sides together
    • Perimeter of a square
      • To find the perimeter of a square you add all of the sides together
    • Circles
      • Chord
      • Diameter
      • radius
      • Sector
      • Circumference
      • Area of a circle
    • chord
      • A line segment with its endpoints on a circle
    • Diameter
      • A line segment that passes through the center of a circle and has its endpoint on the circle
    • radius
      • A line segment with one endpoint at the center of a circle and the other end point on the circle
    • Sector
      • A religion enclosed by two radii and the arc joining their endpoints. ex.A
      A
    • Circumference
      • The distance around a circle
    • Area of a circle
      • The space inside a circle
    • Other polygons
    • hexagons
      • A six sided polygon
    • octagon
      • A eight sided shape
    • Regular polygon
      • A polygon with all congruent sides and angles
