Read and do #10 & #11 (p 33, 34)

Use this!

Read and do #12 - #14 (p. 34)

12. p : the figure is a rectangle q : the figure is a rhombus

Truth table for p ∧ q

13.p : the figure is not a rectangle q : the figure is a rhombus

Truth table for p ∨ q p ∨ q is only false when both p and q are false.

Read and do #15 - #16 (p. 36)
