7th Grade 5/27/2016 • Aim: How can a polygon show symmetry? (7.G.B.5) Do Now – Check homework. Compare and contrast answers. Any questions? Then read page 72. Make observations about both types of symmetry BIG IDEAS You will be able to: • identify if a polygon has reflection and rotational symmetry • Find the line of symmetry or degree of rotation
Mini Lesson • There are two types of symmetry: • Reflection Symmetry – has a line of reflection that splits the polygon into a mirror image • Rotational Symmetry – has a degree of rotation that allows the polygon to be turned to look exactly as it does originally Example
Activity • Classwork Page 73/#A1-3 • Extension Play The quadrilateral Game – Page 74-75 (with geoboards) • Critical Thinking Page 75/#B1-3
Exit Ticket How is reflection symmetry different than rotational symmetry?
