come on its a 4th grade question. "there are _____ pairs of perpendicular lines in a rectangle"

Hi freemath,

First, draw a rectangle. Label it ABCD. (\(\displaystyle \perp\) means "is perpendicular to")

\(\displaystyle AB \perp BC\)

\(\displaystyle BC \perp CD\)

\(\displaystyle CD \perp DA\)

\(\displaystyle DA \perp AB\)

How many pairs do we have?

A good second grader should be able to answer the questions I asked.
 
well, scince a rectangle has four lines that are all right angles, there are ___ right angles. this means that there are ___ (same number) pairs of perpendicular lines.
Rice Krispies :D Good Luck!

I wonder why you're answering a question that 1) has already been answered and 2) was posted back in APRIL!
 
Plus your answer is incorrect, Rice. There are 4 right angles, but 2 pairs of perpendicular lines.
QUIT fooling around :shock:
