Isabella is standing on the corner of Seventh
Street and 8th Avenue, and her sister Kayleigh is
on the corner of First Street and 3rd Avenue.
To ﬁnd her shortest sidewalk route to Kayleigh.
Isabella can simply count blocks. But if Isabella
wants to know her diagonal distance to Kayleigh,
she would need the Pythagorean Theorem to
measure across blocks.

What is the shortest distance from Kayleigh to
Isabella?

Describe how you would identify and ﬁnd the
value of this distance?
