## Konnors Guide Of GeomeryPresentation Transcript

• Konnor's Guide Of Geometry
• You will need to know about :
• Lines
• Angles
• Triangles
• Circles
• Other Polygons
• Lines
• Points
• Line segments
• Rays
• Lines
• Intersecting Lines
• Perpendicular Lines
• Parallel Lines
• Skew Lines
• Points
• A point is a precise location in space. It is labeled with a letter.
Point S S Point M M
• Line segments
• A strait line that can be measured
• Rays
• Strait Line that continues from a point
Point X Point Z
• Lines
• Ex: Train tracks, Horizon
• Intersecting Lines
• Crosses at a point
• Perpendicular
• Two lines that intersects with Four right angles
• Parallel
• Lines that Never cross
• Skew
• Lines that aren't in the same plane
• Angels
• Acute
• Obtuse
• Right
• Vertex/ Vertices
• Straight
• Complementary s
• Vertical
• Acute Less than 90 degrees
• Obtuse Bigger than 90 degrees
• Right = to 90 degrees
• Straight Two right angels. = 180 degrees
• Vertex/ Vertices The point where two lines meet to make a angel Vertex/vertices
• Complementary Two angles when there added they = 90 degrees 45 degrees 45 degrees
• Supplementary Four angles when there added they = 180 degrees
• Vertical Opposite Point K Vertical
• Adjacent Two angles that share a line
• Triangles
• Right
• Obtuse
• Acute
• Scalene
• Isosceles
• Equilateral
• Sum of internal angles
• Perimeter
• Area
• Right One angle of a triangle is 90 degrees
• Obtuse One angle in a triangle has to be 90 degrees
• Acute One angle in the triangle has to be 90 degrees
• Scalene A triangle with no equal sides
• Isosceles A triangle with two equal sides
• Equilateral A triangle that has equal sides 5 cm 5 cm 5 cm
• sum of internal angles The sum of all the angles in the triangle adding up to be 180 degrees 45 degrees 90 degrees 45 degrees 45 45 +90 180
• perimeter The perimeter is the addition is the addition of all the outside sides together 5 in. 30 in. 10 in. 30 in. 10 in. + 5 in. 45 in.
• area of a triangle The area is the length times the width, squared Length 35 in. Width 23 in. 1 35 x23 105 +70 805 402.5 2/ 805.0 -8 00 05 - 4 10 -10 0
• Trapezoid
• Area of a Trapezoid
• Parallelogram
• Area of a Parallelogra m
• Rectangle
• Area of a Rectangle
• Square
• Area of a Square
• Rhombus
• Quadrilaterals A shape with 4 connected sides
• Trapezoid A quadrilateral with two parallel sides
• Area of trapezoid The average of two lengths x the height 35 in. 14 in., 2 35 x14 120 +35 155
• Parallelogram A shape with all opposite sides being parallel
• Area of the parallelogram To get the area of a parallelogram you multiply base x heig ht Base 35 in. Height 25 in. 35 x25 175 +70 875
• Rectangle A quadrilateral with four 90 degree angles
• Area of a rectangle You have to multiply length x width Length 45 degrees Width 15 degrees 45 x15 225 +45 675
• Square A figure that has four sides. All the angles are right. 90 degrees = right angle
• Area of a Square To get to area of a square you x length times width Length 30 in. Width 30 in. 30 x30 00 +90 900
• Rhombus A square with no right angels. All opposite sides are parallel and all opposite angles are congruent.
• Circles
• Chord
• Diameter
• Arc
• Sector
• Circumference
• Area of a Circle
• Chord A line segment with its end points on a circle
• Diameter A line segment that passes through the center of a circle and has endpoints on the circle
• Arc A part of a circle, named by it's endpoints A B
• Radius A line segment with one endpoint on the circle
• Sector A region enclosed by two radii and the arc joining their endpoints The sector
• Circumference The Distance around the circle The distance around a circle is 180 degrees
• Area of a Circle The Space Inside A =3.14xr sq =3.14x10in. =31.40insq. 10 in
• Other Polygons Hexagons Octagons Regular Polygon
• Hexagons A shape with 6 sides and 6 angles
• Octagon A shape with 8 sides and 8 angles
• Regular Polygons All sides are congruent
