Given:

Required:

We need to classify the angles of the given triangle.

Step-by-step explanation:

Recall that an interior angle is an angle that is inside the polygon.

The interior angles of the given triangle are angles that are inside the triangle.

Examples of the interior angles are

$\angle1$
$\angle2$
$\angle3$

Recall that an exterior angle is an angle outside a polygon that forms a linear pair with an interior angle of the polygon.

Examples of the exterior angles of the given triangles are

$\angle4$
$\angle5$
$\angle6$

Recall that the linear pair are two adjacent angles that have the sum of 180 degrees.

$m\angle1+m\angle4=180\degree$
$m\angle2+m\angle5=180\degree$
$m\angle3+m\angle6=180\degree$
