Chapter 1 Exploring Algebraic and Geometric Relationships Objective: Team building and students will be able to classify and identify polygons, use correct terms when describing ideas, identify perimeter and area using multiple methods. Units in 1.2
Name that Polygon 1. Name all the polygons on your handout 2. label one of the polygons on the board
Symmetry Symmetry rigid transformation that appears to map a polygon back on itself Reflection Symmetry when you can reflect an image back on itself exactly, line of symmetry where you can fold the object back on itself Rotation Symmetry when you can turn a figure around a fixed point and get the exact some figure again, called n-fold rotation, need to have 2 or more Translation Symmetry more object left right, up or down
1.1.2 How Can I describe it Definition and properties from the shapes in the polygon bucket Polygon Graphic Organizer Write in pencil what you think to definition of each figure is and the properties Think about what shapes are related Markings on shapes for congruency, parallel, perpendicular
Geometric Parts and Terms Point Has no dimensions, gives a location of a point Named with a capitol letter Line Made up of an infinite number of points, goes on forever in opposite directions Named with any 2 points on the line, with a line drawn above the letters Line Segment Part of a line that has 2 endpoints can be measured The endpoints are the name of the line, with a picture of a line segment above Endpoints Points indicating at the end of the segment Vertex Common endpoint between 2 segments or rays, a corner Measure No symbol above the points indicates that you should measure the distance between the points Ray Part of a line that has only 1 endpoint and goes in one direction forever, named with the endpoint first than any point on ray with a ray symbol above Angle Formed by 2 rays, with a common endpoint, degree measure between the two rays
