After determining the sum оf interiоr аngles оf аny triаngle with your students, you present them with this quadrilateral and ask them to decide the sum of its internal angles without using a protractor.  As the students work, you circulate and monitor what they are working on.  You notice four different approaches so far that the students are taking as shown in the image below.  Select the answer options that are accurate about the different approaches.   Group 1 long description (click to reveal) This group has torn off the internal angles as we explored for the internal angle sum of a triangle.   Group 2 long description (click to reveal) This group has placed a diagonal from the top left corner to the bottom right corner to create 2 triangles.   Group 3 long description (click to reveal) This group has created a triangle off of each side of the quadrilateral which all share a common vertex in the middle of the quadrilateral.   Group 4 long description (click to reveal) This group added three lines to the quadrilateral to create three triangles.  One line drops down perpendicularly from the top left vertex to the bottom side, the second creates a perpendicular line from the first one to the top right vertex.  And the third drops from the top right vertex to meet the bottom line with the first perpendicular line intersects it.
