Triangle A has sides of lengths #36 ,24 #, and #18 #. Triangle B is similar to triangle A and has a side of length #5 #. What are the possible lengths of the other two sides of triangle B?
There are 3 different triangle possible because we do not know which side of the smaller triangle is equal to 5.
In similar figures. the sides are in the same ratio. However in this case, we are not told which side of the smaller triangle has a length of 5. There are therefore 3 possibilities.
