2. Geometry is everywhere by : Laura González

3.  Solid figures are 3D figures that have length, width and heigth.  For example :  Sphere Faces:0 Vertices:0 Edges:0

4.  Cube  Rectangular prism Faces:6 Vertices:8 Edges:12 Conformed by:6 rectangles Faces:6 Vertices:8 Edges:12 Conformed by: 6 squares This is a face it is a flat surface, you will found it in solids.

5.  Triangular prism  Cylinder Faces:5 Vertices:6 Edges:9 Conformed by: 3rectangles and 2 triangles Faces:2 Vertices:0 Edges:0 Conformed by:2 circles and a curved surface An edge is a line segment where 2 or more faces meet.

6.  Cone  Square pyramid Faces:1 Vertices:1 Edges:0 Conformed by: 1circle and a curved surface Faces:5 Vertices:5 Edges:8 Conformed by: 4 triangles and a square This is a vertex where 3 or more points meet This is an equilateral triangle all sides are the same size. Acute angle is the smallest,it has less than 90 degrees

7.  Polygons are closed figures made up of lines segments, they are also plane figures.  For example:  Triangle Vertices:3 Sides:3 In a scalene triangle all sides have different lenght.

8.  Quadrilateral  Pentagon Vertices:4 Sides:4 Vertices:5 Sides:5 Parallel lines never meet A right angle is a square corner It is a rectangle it have 4 right angles and is a poligon.

9.  Hexagon  Octagon Vertices:8 Sides:8 Vertices:6 Sides:6 Intersecting lines allways cross Straight angle forms a straight lines. In this example if the red lines continuous they will Intersect.

10.  Circles are closed and plane figures, usually it have a center, a chord, a radius and a diameter  For example:  Circles The chord is a line segment that connects 2 points of a circle with out passing into the center The diameter is a line segment that pass into the center and connect 2 points The radious is a line segment that connects 1 point and the center The center is a point in the middle of a circle whit the same distance everywhere

11.  Symmetry is when you divide something and you get two congruent figures, each the same size.  For example: Look this figure is congruent. Look this figure, the sides are not congruent.

12.  Similar figures have the same shape and may have diferent size. Isosceles triangle have at least 2 sides whit the same length.

13.  Congruent figures and motion is when you slide, flip or turn a figure.  Slide:is when you move figure in a straight direction. It is a square all sides have the same length and it have 4 right angles

14.  Flip: its the reflection of a figure that gives its image like a mirror  Turn:make a figure move about a point. It is a trapezoid have one pair of parallel lines.

15.  Lines go in 2 directions and it is a straight path of points.  For example  Intersecting lines Obtuse angle is grater than 90 degrees

16.  Perpendicular lines are lines that form right angles Line segment have 2 endpoints also is part of a line.

17.  A ray  point A point is an exact location in space A ray is a part of a line, and it goes in 1 direction.

18.  Angle It is made by 2 rays whit the same endpoint.
