Question

prove that the sum of measures of all angles of a triangle is 180 degree...it should be easy.....SPAMERS STAY AWAY!!!!

Answer 1

Answer: Proof that the sum of the angles in a triangle is 180 degrees. If ABC is a triangle then <)ABC + <)BCA + <)CAB = 180 degrees. Draw line a through points A and B. Draw line b through point C and parallel to line a. ... It is obvious that <)B'CA + <)ACB + <)BCA' = 180 degrees.

• A triangle is a polygon with three edges and three vertices.

• A triangle with vertices A, B and C is denoted as ∆ABC.

• Sum of all angles of a triangle is always 180°.

• The measure of an exterior angle is sum of it's two interior angles that are not adjacent to it.
