Sides of a triangleTry the activity with a partner. What do younotice?1. Cut three pieces of straw so that their lengths are 2 inches, 4 inches, and 8 inches. Then lay them flat on asurface and try to form a triangle. Each end of the straw needs to be connected to another end of a straw.Is it possible?2. You need three pieces of straw that are 4 inches, 5 inches and 7 inches. Then lay them flat on a surfaceand try to form a triangle. Each end of the straw needs to be connected to another end of a straw. Is itpossible?3. Without actually cutting them out, predict whether these three size straws would form a triangle if puttogether.b. 2 in, 4 in, 5 ina. 2 in, 3 in, 5 inc. 3 in, 4 in, 8 ind. 5 in, 5 in, 8 in4. What can you say about the three sides of a triangle?
Sides of a triangle**Triangle inequality rule** Sum of the two smallersides of a triangle must be larger than the thirdside.Ex. Do the following examples create a triangle?1. 13cm, 12 cm, 25cm2. 8ft, 12ft, 7ft3. 9in, 4in, 4in
