## Jasons Guide 2 GeoPresentation Transcript

• Jason's Guide to Geometry
• Lines
• angles
• Triangles
• 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
• 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
• 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
• 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
• 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
