Imagine a triangle with angles of 60*, 70* and a 'trapped' side of 5cm. Is the triangle fixed in shape and size?
Yes. It can only be drawn one way. The reason for this is Angle-Side-Angle (ASA).
Imagine a triangle with sides 5cm and 6cm and a 'trapped' angle of 80*. Is this triangle fixed in shape and size?
Yes. There is only one place to put the last line. The reason for this is Side-Angle-Side (SAS).
Imagine a triangle with sides of 5cm, 6cm and 7cm. Is this triangle fixed in shape and size?
Yes. The three lines fix the size of the triangle, as well as the shape. This reason for this is Side-Side-Side (SSS)
Imagine a triangle with sides of 7cm and 4cm with and angle of 30*, not 'trapped'. Is it fixed in shape and size?
No. The 4cm line can move as far as it wants without affecting the two other things. This is called the 'Ambiguous Case'
Is an RHS (Right-Angle, Hypotenuse, side) angle fixed?
Yes. Pythagoras' theorem can be used to calculate the third side. It is not fixed because of the SSS rule
