  • Mar 29, 2019 · Knowing that the alternate interior angles are equal lets you substitute the angles of the triangle for the angles of the line. Thus we get, Angle ABC + angle BAC + angle ACB = 180°. In other words, in the triangle ABC, angle B + angle A + angle C = 180°. Thus, the sum of all the angles of a triangle is 180°.

Q&A related to Angles Of Triangles. Experts answer in as little as 30 minutes.Let us now talk about the exterior and interior angles of the triangle. 1) Interior Angles. An interior angle is an angle inside the shape. From the above diagram, we can say that the triangle has three interior angles. In this triangle ∠ x, ∠y and ∠z are all interior angles. The sum of the interior angles is always 180° implies, ∠ x + ∠y + ∠z = 180°. Let us see the proof of this statement. Sum of exterior angles = 360 Example. What is the exterior angle of a regular pentagon? Each angle is equal as the pentagon is regular. Therefore, Each angle = 360 5 = 72 3.3 The interior angle of any polygon We know that: in a triangle, interior angles add to 180 ; in a quadrilateral, interior angles add to 360 .

    In the figure, angles 1 and 4 are alternate exterior angles. Alternate Interior Angles: Angles that are on opposite sides of the transversal of two other lines. Both are internal.
