Year 2 Lesson 20 Homework - Page 2

Use the Cartesian Grid sheet (second page) to work these problems:

For each problem draw the line between the 2 points and then the other two lines
that complete the right triangle with this line as the hypotenuse.
For all these problems you must determine these other two triangle side lengths first.
