The possible angles are exterior angles:

$\measuredangle2,\text{ }\measuredangle4\text{ and }\measuredangle6$

The inner angles of the triangle are:

$\measuredangle5\text{ and }\measuredangle1$

We also can see that:

$\measuredangle1\text{ }\cong\measuredangle3\text{ and }\measuredangle2\text{ }\cong\measuredangle4$

Since

$\measuredangle1\text{ and }\measuredangle3\text{ }$

They are vertical angles formed by two intersecting lines, and 1 is congruent to 3. So, 3 is a
