The two triangles have two angles congruent (equal) and the included side between those angles congruent. This forces the remaining angle on our C A T to be: 180 ° - ∠ C - ∠ A. This is because interior angles of triangles add to 180 °. You can only make one triangle (or its reflection) with given sides and angles.
Exterior angle bisector theorem : The external bisector of an angle of a triangle divides the opposite side externally in the ratio of the sides containing the angle. Given : A ΔABC, in which AD is the bisector of the exterior ∠A and intersects BC produced in D.
Rule 2: Sides of Triangle -- Triangle Inequality Theorem : This theorem states that the sum of the lengths of any 2 sides of a triangle must be greater than the third side. Rule 3: Relationship between measurement of the sides and angles in a triangle: The largest interior angle and side are opposite each other.
