Let there be a rotation of d degrees around center 0. Let P be a point other than 0. Select d so that d > 0. Find P'
(i. e., the rotation of point P) using a transparency.

n

step-by-step explanation:

hi there!

the answer will be d: 2

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
