How do you use the converse of the Pythagorean Theorem to determine the type of angle?
Hi yusername :)
he Pythagorean theorem is only for finding the sides of right angled triangles.
If you want to find the angles in a right angled triangle you use basic trigonometry :)
I had a thought.
If you have a triangle ABC with the opposite sides a,b,c then
<B will be obtuse if b^2 > a^2+b^2
<B will be right angles if b^2 = a^2+b^2
<B will be acute if b^2 < a^2+b^2
Thank you Melody, that makes a lot more sense.
