Suppose ab = 10 cm, bc = 9 cm, ac = 11 cm, de = 11 cm, and df = 9 cm. what else do you need to know to prove that the two triangles are congruent by sss?
a.
ef = 9 cm
c.
ef = 10 cm
b.
ef = de
d.
ef = df

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
