Question

In ΔABC, name all the interior and exterior angles of the triangle.

Answer 1

Answer:

∠ABC, ∠BCA and ∠BAC are interior angles

∠YAB, ∠XBC and ∠ACZ are exterior angles

Step-by-step explanation:

Interior Angles :  All the angles that are formed within the polygon are called interior angles.

Here, in Δ ABC    the angles  ∠ABC, ∠BCA and ∠BAC are interior angles as they lie inside the triangle.

Exterior Angles: All the angles which are formed outside the polygon by an exterior of line segments are called exterior angles.

Here, in Δ ABC    the angles  ∠YAB, ∠XBC and ∠ACZ are exterior angles as they lie outside the triangle.
