- 2What is the formula for Pythagoras Theorem?Enter text here...
- 3How do you Work out the hypotenuse of this triangle.12²+5²=c²
144+25=c²
169=c²
c=√169
c=13
- 4How do you work out the shorter side of this triangle?20²+z²=25²
400+z²=625
625-400=z²
z=√225
z=15cm
- 5How do you work out the triangle with only one measurement. Both unnamed sides are equal to aa²+a²=25²
2a²=625
2a²÷2=625÷2
a²=312.5
a=√312.5
a=17.68(2dp)
- 6How do you test if a triangle is right angled?3²+4²=9+16
=25
