3. Find the distance between the points (2, 1) and (10, 7)
Find the distance between the points (2, 1) and (10, 7). You would not think that this was a Pythagoras question, but…
(10, 7)
(2, 1)

4. Find the distance between the points (2, 1) and (10, 7)
Find the distance between the points (2, 1) and (10, 7). You would not think that this was a Pythagoras question, but…
(10, 7)
7 – 1 = 6
(2, 1)
10 – 2 = 8
