Question

interior of a trangle
​

Answer 1

Answer:

The interior of the triangle is the set of all points inside a triangle, i.e., the set of all points in the convex hull of the triangle's vertices. ... If the hull has three points, the point lies in the triangle's interior; if it is four, it lies outside the triangle.

Answer 2

Interior angles of a triangle sum up to 180°.

Proof,

Interior angles sum of a polygon = (n-2)x180°

{n=the number of sides}

=(3-2)x180

=1x180

=180°
