Standard 6.4.2: I can use the properties of complementary, supplementary, and vertical angles to solve problems involving and unknown angle.  I can justify my solutions.

2.  a. – d.  7th Grade P.5

Standard 6.4.4: I understand that the sum of the interior angles of any triangle is 180° and the sum of the interior angles of any quadrilateral is 360°.  I can use this information to solve problems.

3.  a. – b.  6th Grade Z.10

c.  6th Grade Z.10 and 7th Grade P.4

Standard 6.5.4: I understand the concept of the constant  as the ratio of the circumference to the diameter of a circle.  I develop and use the formulas for the circumference and area of a circle.

Standard 6.5.5: I know common estimates of  (3.14, ) and use these values to estimate and calculate the circumference and area of circles.
