On p. 433, the drawing of a sandbox uses a scale of 1 unit=12 inches, Reproduce the drawing with a scale of 1 unit=24 inches.
Show drawing to Mrs. ALter to see if it matches up (width would be 3 squares on each side)
Tell me the two definitions of complementary angles and supplementary angles. YOU MUST give the correct definition for BOTH in order to get the full points.
Complementary angles: angles that add up to 90 degrees
Supplementary angles: angles that add up to 180 degrees
Write and solve an equation to find the value of y. (Mrs. Alter will do drawing on the board)
Equation: 120+3y
Answer: y=20
Draw a pair of supplementary adjacent angles. Label the measures of the angles.
Mrs. Alter will check to see if drawings look like adjacent angles and measures are correct.
