I had to do questions 2, 7, 14 and 18.
2.) A triangle has side lengths of 7cm, 11cm, & 15cm. Explain how you can determine whether it or not it is a right triangle.
" a² + b² doesn't equal to c². This isn't a right triangle "
7.The sides of a right triangle measure 9cm,12cm and 15cm.
a)What is the area of each square attached to three sides of the right triangle?
b)Write an addition statement showing the relationship between the areas of the three squares.
