knowing one angle and subtracting it by 180°.
adding 180°
Again... ask Mr. Maguire
5
Can the Pythagorean Theory only work for right angle triangles?
Nope... well maybe
Yes, of course!
Only if we are including squares
No
6

7
Can a Isosceles triangle also be Obtuse?
How would I know?

Only if it is an open triangle
Yes...
