Given: zabc and zfgh are right angles; ba || gf; bc gh
prove: a abc afgh
step 1: we know that zabc 2 zfgh because all right angles
are congruent.
step 2: we know that zbac gfh because corresponding
angles of parallel lines are congruent.
step 3: we know that bc gh because it is given.
step 4: a abc afgh because of the
asa congruence theorem.
aas congruence theorem.
third angle theorem.
reflexive property.

Which property is illustrated by the following statement? if hxa rgi, then rgi hxa.

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30 ∘c on monday, but decreased at a constant rate in the next 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
