Examples of points ,planes and intersections in everyday life | page 4....Angles | page 5 ... Angles in everyday life | page 6...Angles and Segment Bisectors | page 7 .....Everyday Angles and Bisectors | page 8......More Angles | page 9.....Angles we see everyday | page 10...... parallel lines and angles formed by transversal | page 11...Look what I found | Page 12.....Perpendicular Lines | page 13....more perpendicular lines | page14.....triangles | page 15....triangles in our life | pages 16....pythagoream Theorem | page17....in everyday life | page 18... congruent triangles page 19... proving triangles are congruent page 20.................. poleygons page 21... we use them eceryday page 22... geometrical terms page 23... real life example

2: by a small dot | Point- a point has no dimensions . It is represented | Plane- has two dimensions and looks like a floor or wall | page 2 | Intersect | In geometry ,figures intersect if they have any points in common

3: point | plane | Intersect | page 3 | Everyday life

4: Angles an angle consists of two rays with the same end point | Acute Angle | an acute angle measures between 0* and 90* | An obtuse angle measures more then 90* but less than 180* | Right angle an internal angle that equals 90* | straight angle | an angle that measures 180* | page 4

5: straight angle | Right Angle | obtuse angle | Angles in everyday life | Acute Angle | page 5

6: Angles and Segment Bisectors | Segment Bisectors | A segment,ray,line or plane that intersects a segment at its midpoint | Complementary Angles two angles are complementary if the sum of their measure is 90* | the sum of their measure is 180* | Supplementary Angles | page 6

7: page 7 | Everyday Angles and segment bisectors

8: Complementary Angles-If the sum of there measures is 90 Degrees | Supplementary Angles | Vertical Angles Two Angles that are not adjacent and whose sides are formed by 2 intersecting lines | Two angles whose measures have a sum of 180` | pg 8

9: Angles in our life | Vertical | Supplementary | Complementary | pg 9

10: parallel lines two lines that lie in the same plane and do not intersect | angles formed by transversal | a line that intersects two or more coplanar lines at different points | pg 10

11: Look what I found | parallel lines | angles formed by transversal | pg 11

12: perpendicular lines lines that intersect to form a right angle | pg12

13: Perpendicular lines | pg 13

14: Triangles | a figure formed by three segments joining three noncollinear points | equilateral triangle has 3 congruent sides always 60* | Isosceles has at least 2 congruent sides | scalene =3 unequal sides | pg 14

15: Fun with Triangles | pg 15

16: Pythagorean Theorem ------- | the sum of the areas of the two squares on the legs( a and b)equals the are and the square on the hypotenuse | Distance formula If A(x,y)and B(x2y2) are points in a coordinate plane then the distance between A and B = (x2-x1=(y2y1) | pg 16

17: In Everyday life | pg 17

18: Congruent Triangles | congruent triangles--- are congruent when all corresponding sides and interior angles are congruent .triangles will be the same size and shape but one side may be a mirror image of the other | pg18

19: PROVING TRIANGLES ARE CONGRUENT | SIDE ANGLE SIDE RULE IF TWO SIDES AND THE INCLUDED ANGLE ARE CONGRUENT TO TWO SIDES AND THE INCLUDED ANGLE OF A SECOND ANGLE THEN THE TWO TRIANGLES ARE CONGRUENT | pg 19

20: Polygons a plane figure that is formed by three or more segments called sides.Each side intersects exactly two other sides at each of its endpoints .Each endpoint is a vertex of the polygon. | parallelogram -a quadrilateral with both pairs of opposites parallel | rhombus-a parallelogram with four congruent sides | Rectangle a parallelogram with four right angles | square- a parallelogram with four congruent sides and four right angles

21: polygons | parallelograms | Rhumbus | Retangle | square | we use them everyday

22: Geometrical terms | 1.pyramid-A polyhedron in which the base is a polygon and the lateral faces are triangles with a common vertex. | 2 Rotational symmetry -the figure in the plane has rotational symmetry if the figure can be mapped into its self of a rotation of 180* or less | 3 scale factor | heptagon -a polygon with 7sides | secant-a line that intersects a circle in 2 points | pg 22

23: secant | pyramid | rotational symmetry | scale factor | heptagon | pg 23
