Example 1:
The sides are 6cm, 7cm and 8 cm.
6cm + 7cm = 13cm > 8 cm
6cm + 8cm = 14cm > 7cm
8 cm + 7cm = 15cm > 6cm
I think you can draw them yourself. Draw a triangle and label it's sides.
Example 2:
The sides are 6cm , 6cm and 6cm.
6cm + 6cm = 12cm > 6cm
6cm + 6cm = 12cm > 6cm
6cm + 6cm = 12cm > 6cm
Example 3:
The sides are 3cm, 4cm and 5 cm.
3cm + 4cm = 7cm > 5cm
4cm + 5cm = 9cm > 3cm
3cm + 5cm = 8cm > 4cm
Example 4:
The sides 5cm, 12cm and 13 cm
5cm + 12cm = 17cm > 13cm
5cm + 13cm = 18cm > 12cm
13cm + 12cm = 25cm > 5cm
Example 5:
The sides are 8cm, 8cm and 8cm.
8cm + 8 cm = 16cm > 8cm
8cm + 8 cm = 16cm > 8cm
8cm + 8 cm = 16cm > 8cm
Hope this helps you......
