How do you find Angles in a Polygon ? For a square, pentagon, hexagon, heptagon, octagon, table the sum of interior angles in a list. Describe what you have seen. different starting points. How do you measure or draw angles? When you look at the sum of interior angles of different polygons can you see a pattern? What are the sum of Angles in triangles & Quadrilaterals You Choose What is the connection between the number of sides of a polygon and sum of angles? How about a regular decagon? Draw a Pentagon measure angles, add them up. Repeat for a hexagon. Which is the most efficient method of finding the sum of angles in a polygon? back

Learning Journey Angles in a Polygon Which is the most efficient method of finding the sum of angles in a polygon? Compare and discriminate between ideas Why might this be useful? What connection between sides and sum of angles? Predict, draw conclusions What will the sum of the angles in a 7 sided shape be? An 8 sided? Can you work out for a ten sided? Etc? How about a regular decagon? Seeing patterns Can you see a pattern in what you have done? Put sum of interior angles in a list. Describe what you have seen. Use information Grasp meaning Draw a Pentagon measure angles, add them up. Repeat for a hexagon. Observation and recall of information Regular? Angles in triangles & Quadrilaterals How to measure angles.
