Right Angle
How can I use a calculation that verifies there is a right-angle in my triangle?
I have a triangle which is whose sides are 5cm, 12cm and 13cm.
How can I use a calculation that verifies there is a right-angle in the triangle?
And how do I calculate the size of the smallest angle in the triangle?
Cheers
The Pythagorean states that for the 3 sides of a right triangle (2 legs and a hypotenuse - c):
a^2 + b^2 = c^2
In this case 5^2 = 24
12^=144
13^2 = 169
and 25 + 144 = 169
So you do have the Pythagorean relationship.
The legs aree 5cm and 12cm - the hypotenuse is 13 cm.
