ANSWER #3

1. Write each of the following in "If p, then q" form.
a. Every square is a rectangle.
b. Being older than 30 is sufficient to show that I am at least 21.
2. Write the converse, inverse and contrapositive of: "If we have a quiz today, then we will not have
a quiz tomorrow.
3. Determine whether the given statements are equivalent.
a. If a = b, then a · c = b.c
If a + b, then a · c + b ·c
b. If I live in Nashville, then I live in Tennessee.
If I do not live in Tennessee, then I do not live in Nashville.
4. Write the contrapositive of each statement and use he contrapositive to determine whether the
original statement is true or false.
a. If 3 + x is an odd integer, then x is an even integer. (Assume x is an integer)
b. If two triangles are not similar triangles, then they are not congruent triangles.
Note: Similar triangles have the same shape. Congruent triangles have the same size and
shape.
c. If today is not Wednesday, then tomorrow is not Thursday.
