GOOGLE MAPS MINI PROJECT

 Students will build a triangle around a point in such a way that this point becomes the circumcenter. They must know what the circumcenter represents (center point of a triangle, where all vertices are the same distance away). After picking a city to represent their center, students will measure out 3 different spots that are each the same distance from their origin. They will connect these spots to make a triangle. PROJECT OVERVIEW

 CCSS.MATH.CONTEN T.HSG.C.A.3 Construct the inscribed and circumscribed circles of a triangle, and prove properties of angles for a quadrilateral inscribed in a circle. CCSS.MATH.CONTEN T.HSG.C.A.3  Connect the circumcenter to the real-world. Construct a circumcenter in reverse  Intended Grade: 10 th grade, Geometry CP STANDARDS AND OBJECTIVES

5 classes. 2-3 days to learn material, 1 day to complete project, 1 day to present in groups TIMELINE

 There will be 3 layers of the project:  Origin and Markers  Polygons  Radii  Students pick an origin point to represent the circumcenter  Use knowledge of radii and the definition of circumcenter to construct a triangle around this point  Connect the 3 circle- points to make the triangle  Make 2 triangles: acute and obtuse ACTIVITIES

 Graded based on whether having all components of their maps, as well as their summary of the center. They will be placed in groups, where they will present their project (on their own device) to each other in a pair-share.  Students can extend their thinking by constructing any of the other 3 special triangle centers (incenter, orthocenter, or centroid).
