What is Right angled triangle ?

Right angled triangle is a triangle in which one angle is a right angle or two sides are perpendicular

Pythagoras Theorem ;

[tex]BC^2+AC^2=AB^2[/tex]

We have,

Right angled triangle [tex]\triangle ABC[/tex] right angled at [tex]C[/tex],

[tex]AC=22cm[/tex] and [tex]BC=8cm[/tex]

So, using Pythagoras Theorem,

[tex]BC^2+AC^2=AB^2[/tex]

[tex]8^2+22^2=AB^2[/tex]

⇒ [tex]AB^2= 64+484[/tex]

[tex]AB^2=548[/tex]

[tex]AB =\sqrt{584}=2\sqrt{146}[/tex]

[tex]AB=24.166\ cm[/tex]

So, the value of [tex]AB[/tex] is  [tex]24.166\ cm[/tex] or [tex]2\sqrt{146}[/tex] cm which is find out using Pythagoras Theorem.

Hence, we can say that the length of [tex]AB[/tex] is [tex]24.166\ cm[/tex] or [tex]2\sqrt{146}\ cm[/tex].
