The truth is not hidden : 

The truth is not hidden 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. : 

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

1. POINTS : 

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 : 

ANGLE DEFINED ANGLE RELATIONSHIPS Intersecting lines 3 WAYS TO DESCRIBE AN ANGLE INTERSECTING/PARALLEL

Polygons: plane closed figure made up of straight line segments. : 

Polygons: plane 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 : 

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. : 

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 throught 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 boredered by two radiii and the arc they intercept. Central Angle: verses inscribed angle…center point vs. point on circumference. What is pi? Ratio Circ: diameterr 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 : 

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 : 

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

NOW THE TRUTH : 

NOW THE TRUTH HAS TOTALLY BEEN REVEALED. IF YOU MISSED IT, THEN YOU ARE ONLY HUMAN!
