Finding the Missing sides


Use this to find all the missing sides. For the homework, you will notice that all the problems on the page are missing side c. This means all your equations will have 'a' and 'b' filled in, with c missing. Just add the two on the left, and take the square root.

For a triangle with sides 9 and 12, filled into the equation it gives


81+144 = c2
225 = c2
225 = c
15 = c

Same thing for the other equations.
