The coordinates of the vertices of a def are d(-4,1), e(3. – 1), and f(-1, – 4)
which statement correctly describes whether a def is a right triangle?
o
a def is not a right triangle because no two sides are perpendicular.
a def is a right triangle because de is perpendicular to ef
a def is a right triangle because df is perpendicular to ef
a def is a right triangle because de is perpendicular to df

ΔDEF is not a right triangle because no two sides are perpendicular.

Step-by-step explanation:

The coordinates of the vertices of ΔDEF are given to be D(-4,1), E(3,-1) and F(-1,-4).

Now length of DE is given by units

length of EF is given by units

and length of FD is given by units.

Therefore, 53 ≠ 25+34

Hence, the length of the sides does not support the Pythagoras theorem.

So, ΔDEF is not a right triangle because no two sides are perpendicular. (Answer)

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

6e14 is the answer.
