1.) What does it appear to you that the sum of the 3 angles is?
2.) Have you tried this yourself with different quadrilaterals? If so, then what is your conclusion?
3.) Label the interior angles of the triangle (what is their sum?), observe that they are supplementary to the outer angles, and add all 3 pairs. What do you find?
I like literally have trouble even understanding that, I know it is a lazy approach but would anyone just be able to give me the answer. I am terrible with maths, my only guess for the first one would be that the sum of the angles is 180 degrees considering that it is a triangle.
