Assessment activities: 5.1. Triangle Inequality

Construct, using the appropriate GeoGebra tools, a triangle with sides of 3, 4, and 5 [i]u[/i], where [i]u[/i] is the unit of length defined by the grid. [br][br]Then, do the same for the triangles with the data provided below.[br][br]Have you noticed anything unusual? Why do you think this happens? Formulate your own conjecture about what you observe.
a) 3, 4 and 8 [i]u[/i][br]
b) 3, 4 and 6 [i]u[/i][br][br]
c) 3, 4 and 7 [i]u[/i].[br][br]
d) 9, 5 and 3 [i]u[/i]
e) 7, 5 and 3[i] u.[/i]
f) 8, 5 and 3[i] u.[/i]
g) 6, 9 and 3 [i]u.[/i]
h) 6, 10 and 3[i] u.[/i]
