Triangle KNM is isosceles where angle N is the vertex.What is the measure of angle K? Angle Relationships Triangle KNM is isosceles where angle N is the vertex. What is the measure of angle K ? B. 25. Consider the diagram and proof by contradiction. Given: ABC with AB ≅ AC (Since it is given that AB ≅ AC it must be true that AB = AC. Assume ∠B and ∠C are not congruent.)

Now by angle sum property of a triangle we get: ang K +ang I + ang J = 180°. 70° + I + 58° = 180°. This is because all three angles in an isosceles triangle must add to 180° For example in the isosceles triangle below we need to find the missing angle at the top of the triangle . The two base angles are opposite the ma...
