Question

Next, find the length of BC. Place point F at (4,4), and draw BF and FC. Find BF and FC using the coordinates of B, C, and F. Then use the Pythagorean Theorem to find BC.

Answer:

BC = 5

Explanation:

Of course, this geometry program can tell you the length of BC.

If you follow directions, you get a right triangle BCF that has leg lengths 3 and 4. The Pythagorean theorem then tells you the length of hypotenuse BC is ...

BF = 4 -1 = 3

FC = 4 -0 = 4

BC² = BF² +FC²

BC² = 3² +4² = 9 +16 = 25

BC = √25

BC = 5
