make a sketch !!!
a diagonal would for example be from B to D
change in x = 1 - -1 = 2
change in y = -3 - +3 = -6
sqrt (2^2+6^2) = sqrt 40
= 2 sqrt 10
1. Find the length of a diagonal of a rectangle ABCD with vertices, A (-3,1), B(-1,3), C(3,-1) and D (1,-3).
A) 5.7
B) 6.3
C) 3.2
D) 4.5
Hello! I don't understand how to solve this question since the unit I just read barely went over this. If anyone could help that would be great. Thank you so much!

the answer is 6.3
anyone have the answers to the entire test...
Geometry A semester exam:
#1: When the net is folded into the pentagonal prism shown beside it, which letter will be on the bottom left side if A is facing frontward, G is top right, and F is bottom right?
Answer: D will be on the bottom left
#2: How are <1 and <2 related?
Answer: A- they are supplementary
#3: Find the midpoint of PQ
Answer: (3,2)
#4: Find the length of a diagonal of a rectangle ABCD with vertices A (-3, 1), B (-1, 3), C(3, -1), and D (1,-3).
Answer: 6.3
#5: What is the inverse of the following conditional?
Answer: If n is not even, then n is not the sum of two even numbers.
Hope this helps:)
