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
