Check the slopes
the first 2 points have slope (3-1) / (5-1) = 2/4 = 1/2
points 2 and 3 slope = 4/2 = 2
3 and 4:- slope = -2/-4 = 1/2
4 and 1:- slope = 4/2 = 2
so we have 2 pairs of opposite sides which are parallel
looks like a parallelogram or a rhombus
if adjacent sides are equal its a rhombus
length betwee pts 1 and 2 = sqrt(2^2 + 4^2) = sqrt20
.. ... ... .. .. .. ...2 and 3 = sqrt(4^2 + 2^2) = sqrt20
so it is a rhombus
Answer:B
Step-by-step explanation:
Answer:
a.) 102 b.) 99.4
Step-by-step explanation:
a. 34 x 3 = 102
b. 7[62 ÷ (52 − 42) + 8] = 
or 
or 99.4
Answer:
13
Step-by-step explanation:
39 divided by 3 = 13
52 divided by 4 = 13
65 divided by 5 = 13
so therefore, the constant of proportionality is 13
