Answer 1

Corollary 3.5.4 states that the angle sum of any convex quadrilateral is less than or equal to 360 degrees. The measure of an exterior angle of a triangle is greater than or equal to the sum of the measures of the two opposite interior angles.

Step-by-step explanation:

Corollary 3.5.4 states that the angle sum of any convex quadrilateral is less than or equal to 360 degrees. The proof for this corollary is left as an exercise.

The measure of an exterior angle of a triangle is greater than or equal to the sum of the measures of the two opposite interior angles. This can be proven by considering the triangle's interior angles and using the fact that the sum of the measures of angles in a triangle is always 180 degrees.
