Question

Mary is explaining the angle relationship of the interior angles of triangles to a coworker. She states that the angles should always add up to 180°. How can Mary prove that this is true? (Hint: Imagine taking the angles and putting them side by side.)

Answer 1

Answer:

I can't show you full diagram but I can give him details

Step-by-step explanation:

using a square divide it into two equal diagonal parts forming a triangle and knowing the total number of angles in a square is equals to 360 dividing it in a diagonal section once will result in 180 degree which therefore means that half of a square which makes a triangle is 180 degree

Answer 2

Answer:

There are three angles in a triangle. Each angle can be cut off and arranged to be adjacent angles, with each vertex on a straight line. This shows that the sum of all three measures of interior angles will always add up to 180°.
