Onlinetutorsite Inc Welcomes You To The World Of Math's:

Onlinetutorsite Inc Welcomes You To The World Of Math's In the world of shapes, there exists simple truths. From every angle, there are rules. These rules, if followed, will bring you correct answers & great happiness . In math, all secrets are revealed.

Geometry is the study of figures.:

Onlinetutorsite.com Geometry is the study of figures. Plane geometry studies figures in a flat, two dimensional space called a plane. Polygons-Triangles, Quadrilaterals…. Perimeter and area Circles Solid geometry studies figures in a three-dimensional space. Coordinate Geometry Volume

1. POINTS :

Onlinetutorsite.com 1. POINTS 2.LINES AND THE ANGLESTHEY FORM 3. INTERSECTING LINES AND RULES ABOUT ANGLES FORMED A LINE IS a continuous set of points having 1 dimension length. A POINT has no dimension and only position. A LINE SEGMENT IS a part of a line ANGLE DEFINED: space formed when two lines meet at a point, Parallel lines ANGLE RELATIONSHIPS (adjacent/complementary) Intersecting lines (vertical/supplementary angles) 3 WAYS TO DESCRIBE AN ANGLE

INTERSECTING/PARALLEL :

Onlinetutorsite.com Angle relationships for intersecting lines Angle relationships for parallel lines 1) Angles opposite Each Other Are Equal and Called Vertical Angles Corresponding Angles Defined 2) Angles Adjacent to Each Other Are Supplementary Parallel Lines Are Defined Perpendicular Lines Intersect Are Right Angles Alternate Interior Angles formed by transverse lines. INTERSECTING/PARALLEL

Polygons: Plane Closed Figure Made Up Of Straight Line Segments.:

Onlinetutorsite.com Remember type is defined by number of sides…3/triangle, 4/quadrilateral, 5/pentagon, 6/ hexogon … Differences Shared Principles Similar verses Congruent: Angles equal/sides proportional vs. angles equal but sides same size and shape Sum of the Angles= (N-2) X 180 Each angle is #/N (because number of sides=number of angles.) Polygons : P lane Closed Figure Made Up Of Straight Line Segments.

Angles equal/sides proportional vs. Angles equal but sides same size and shape equal but sides same size and shape:

Onlinetutorsite.com Angles equal/sides proportional vs. Angles equal but sides same size and shape equal but sides same size and shape Similar vs. Congruent Polygons

Circles : A plane closed figure formed by a set of points equidistant from a fixed point called the center.:

Onlinetutorsite.com Circles : A plane closed figure formed by a set of points equidistant from a fixed point called the center. Important terms Circumference: boundary Radius: distance from center to any point on circumference. Diameter-line segment passing through the center and ending on both ends at circ. Chord: line segment having both endpoints on circ….longest one is diameter Secant: line passing through the circle interesting it at 2 points Tangent: line intersecting the circle at only one point. Radius from that point is perpendicular to the tangent. Arc: a part of the circ. Semi- Cirlce - an arc that is ½ the circumference. Sector: The interior part of circle bordered by two radii and the arc they intercept. Central Angle: verses inscribed angle…center point vs. point on circumference. What is pi? Ratio Circ: diameter of a circle! So pi X diameter=circ The area of a circle: A= pi r squared Pi= 3.14 or 3.1 or 3 1/7 or 22/7

Coordinate Geometry:

Onlinetutorsite.com Coordinate Geometry Locates geometric figures on planes via Cartesian Coordinate System. If only x and y then it is two dimensions. If x, y and z then it is no longer on a plane but in space, so it is three dimensional. With x and y only, then two planes are divided into 4 quadrants. (I, 11, 111 and 1V) Distance Sq.: (x2-x1)squared + (y1-y2)squared So the square root of the dist= square root of above Midpoint x1 + x2 /2, y1+y2/2= x midp ..y midp . Slope: m = y2-y1/X2 - X1

Volumes on Volumes:

Onlinetutorsite.com Volumes on Volumes Shape Cubes Cylinders Pyramids Cones Sphere Formula V= e cubed V=pi r squared h V=1/3lwh V=1/3 pi r squared h V=4/3 pi r cubed
