7A: Angle Relationships

I can find unknown angle measures by reasoning about adjacent angles with known measures.I can recognize when an angle measures 90∘, 180∘, or 360∘.I can recognize when adjacent angles are complementary or supplementary.I can find unknown angle measures by reasoning about complementary or supplementary angles.I can determine if angles that are not adjacent are complementary or supplementary.I can explain what vertical angles are in my own words.I can reason through multiple steps to find unknown angle measures.I can recognize when an equation represents a relationship between angle measures.I can write an equation to represent a relationship between angle measures and solve the equation to find unknown angle measures.

7B: Drawing Polygons with Given Conditions

I can show that the 4 side lengths that form a quadrilateral can be rearranged to form different quadrilaterals.I can show that the 3 side lengths that form a triangle cannot be rearranged to form a different triangle.I can show whether or not 3 side lengths will make a triangle.I can reason about a figure with an unknown angle.I understand that changing which sides and angles are next to each other can make different triangles.Given two angle measures and one side length, I can draw different triangles with these measurements or show that these measurements determine one unique triangle or no triangle.Given two side lengths and one angle measure, I can draw different triangles with these measurements or show that these measurements determine one unique triangle or no triangle.

7C: Solid Geometry

I can picture different cross-sections of prisms and pyramids.I can explain that when a three-dimensional figure is sliced it creates a face that is two dimensional.I can explain why the volume of a prism can be found by multiplying the area of the base and the height of the prism.I can calculate the volume of a prism with a complicated base by decomposing the base into quadrilaterals or triangles.I can picture the net of a prism to help me calculate its surface area.I can find and use shortcuts when calculating the surface area of a prism.I can decide whether I need to find the surface area or volume when solving a problem about a real-world situation.I can solve problems involving the volume and surface area of children’s play structures.
