Find the length of the base of
triangle B.
So the first thing we want to do is
check out the scale of our axes. And we can see that every square is
equal to one unit, and that’s because we have two squares is equal to two units,
four squares is equal to four units, etcetera. Therefore, if we count along the
base of our triangle, we can see that the length of it is going to be five length
units long. And it is also worth noting that we
could’ve seen the vertices of the bottom of our triangle and found out what their
𝑥-coordinates were, so in this case, it’s five and 10. Then we could’ve found the
difference between them. So 10 minus five gives us five,
which would have given us the same result.
