Which characteristics will prove that ? def is an isosceles triangle? segment de and segment ef are congruent to each other but not to segment df, and their slopes are not related. segment de and segment ef are congruent, and their slopes are opposite reciprocals. segment de is larger than segment ef, and their slopes are not related. segment de is larger than segment ef, and their slopes are opposite reciprocals.

Option A: Segment DE and segment EF are congruent to each other but not to segment DF, and their slopes are not related.

Step-by-step explanation:

Isosceles Triangle is a type of triangle in which 2 of the 3 sides are of exactly the same length. All isosceles triangles should have at least 2 sides to be equal. In the given triangle DEF, the sides include DE, DF, and EF. As mentioned, two of the sides out of three should be same. So 3rd and 4th options can be safely rules out. It is also important to note that the fact that two sides should be equal does not depend on the slopes of the lines. The angles can be of any size. That is, the triangle to be isosceles does not depend on the angles or the slopes of the lines. This means option B is also incorrect. So the correct choice is Option A!!!

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
