Triangles

Hanka cut the 20 cm long straws into three pieces each piece had a length in cm. Then, with these three pieces, she tried to make a triangle.

a) What circuit has each of the triangles?
b) How long can the longest side measure?
c) How many different triangles could be made?

Result

o =  20 cm
a =  9 cm
n =  8

Solution:

Solution in text o =
Solution in text a =
Solution in text n =
