a). The numbered angles 4, 6, 8 and 10 are exterior angles
b). Remote exterior angles for interior angles 1 and 5 are the angles 4 and 6.
Remote exterior angle for interior angle 3 is angle 8
Remote exterior angle for interior angle 2 is angle 10.
c). The two exterior angles that share the same remote interior angles are 4 and 6.
When two straight lines intersect, they form angles that have important properties, especially when considering the angles created with the formation of a triangle.
The interior angles of a triangle are the angles formed inside the triangle by its three sides.When two straight lines intersect, they form four interior angles, and when these lines form a triangle, the interior angles are the angles within the triangle itself.
The exterior angles of a triangle are the angles formed outside the triangle, but adjacent to its sides.When a triangle is formed by two intersecting lines, each of the lines extended beyond the point of intersection forms two exterior angles.
In conclusion, the angles 4, 6, 8 and 10 are the exterior angles, angles 1, 2 and 3 are the interior angles and the angles 4 and 6 are exterior angles that share the same remote interior angles of 1 and 5.
