A half times a half is a quarter. You can think of it this way: 1/2 is equivalent to 0.5, so you do 0.5 times 0.5 which is 0.25.(answer)
Answer:
Red and Green are parallel
Black and Blue are perpendicular
Step-by-step explanation:
Parallel lines need to have the same slope. Lines red and green both have a slope of 1/2.
The slopes of two lines that are perpendicular have to be opposite reciprocals, and must be multiplied together to get -1. Line black has a slope of -4, and line blue has a slope of 1/4. Both of them multiplied together equals -1.
