Answer: Angle AFB & BFC
Step-by-step explanation:
Supplementary angles are when two angles form 180 degrees (in other words when two angles add up to make a straight line)
Let’s look at the first option: Angels CFD & CFE:
When you add both of these angles they add up to a 90 degree angle so we know that they aren’t supplementary angels because they don’t add up to 180 degrees
Now let’s look at the second option (our answer): angels AFB & BFC:
When you add both of these angels up you can see that they make a straight line, which is 180 degrees, they make up a supplementary angle
Let’s look at the third option: Angles BFD & BFC:
By looking at the angles you can see that they almost make up a 180 degree angle, but it’s not quite there l so therefore the angles are not supplementary
And finally our last option: Angels AFB & DFE:
When we look at these angles we can see that together these to angles make more than a 180 degree angle because it is bigger than a straight line, therefore they are not supplementary angles
So your answer is option 2: Angles AFB & BFC
