Unit 8 Geometry 

Essential Questions
How can you use geometric components and/or figures to create new figures? • How could attributes be used to justify the classification or naming of plane figures? • What are the relationships between the parts of the circle? • How can the decomposing and recomposing of shapes help calculate perimeter, area, and volume? • What would influence your decision in choosing a unit of measure? 
Learning Outcomes;
• Identify and describe the diameter, radius, chord, and circumference of a circle. • Classify and measure angles (right, acute, obtuse, and straight). • Identify appropriate tools used to measure and draw angles and triangles. • Solve addition and subtraction problems to determine unknown angle measures on a diagram in practical problems. • Classify triangles according to sides and angles. • Compare and contrast the properties of triangles. • Identify congruent sides and right angles using geometric markings to denote properties of triangles. • Use models to prove that the sum of the interior angles of a triangle is 180 degrees, and use that relationship to determine an unknown angle measure in a triangle. • Apply transformations to polygons in order to determine congruence. • Recognize that translations, reflections, and rotations preserve congruency. • Identify the image of a polygon resulting from a single transformation (translation, reflection, or rotation). • Investigate and describe the results of combining and subdividing polygons. • Compare and contrast the characteristics of a given polygon that has been subdivided with the characteristics of the resulting parts
