Question

Draw any triangle on a paper. Name its vertices A, B, C. Measure the lengths of its three sides using a divider and scale and enter them in the table.

Length of side	Sum of the lengths of two sides	Length of the third side
l (AB) =         cm	l (AB) + l (BC) =         cm	l (AC) =         cm
l (BC) =         cm	l (BC) + l (AC) =         cm	l (AB) =         cm
l (AC) =         cm	l (AC) + l (AB) =        cm	l (BC) =         cm

Answer 1

 

Length of side	Sum of the lengths of two sides	Length of the third side
l (AB) = 2.7 cm	l (AB) + l (BC) = 6.6 cm	l (AC) = 5.6 cm
l (BC) = 2.9 cm	l (BC) + l (AC) = 9.5 cm	l (AB) = 2.7 cm
l (AC) = 5.6 cm	l (AC) + l (AB) = 8.3 cm	l (BC) = 3.9 cm
