The coordinates for side BC in polygon ABCD are (2,5) and (5,5). What is the length of side BC?
A.
3 units
B.
5 units
C.
7 units
D.
10 units
To find the length of side BC, we use the distance formula:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Given the coordinates (2,5) and (5,5) for points B and C respectively:
d = √((5 - 2)^2 + (5 - 5)^2)
d = √(3^2)
d = √9
d = 3 units
Therefore, the length of side BC is 3 units.
So, the correct answer is:
A. 3 units
