Angle Sum Property Of A Triangle (Theorem & Proof)
WebExterior Angle of a Triangle. Angle x is an exterior angle of the triangle: The exterior angle of a triangle is equal to the sum of the interior angles at the other two vertices. In other … WebProof 2 (The Pythagoreans) The Pythagorean proof is even simpler. A line parallel to the base BC is drawn through the vertex A, which gets us two pairs of alternate angles: CBA, DAB and BCA, EAC. Now, angle BAC complements, on the one hand, ∠CBA + ∠BCA to the sum of the angles of D ABC, and, on the other, ∠DAB + ∠EAC to two right angles.
