They are co-terminal angles.
Those are a pair of 'supplementary' angles.
Adjacent angles have a shared vertex.
A shape with ten sides and seven vertex is impossible. There must always be the same amount of sides as vertex in a shape.

Yes. If the two acute angles have their measures add up to 90 degrees, and both angles share one side that is common to each angle (they are adjacent), then their non-common sides will be perpendicular.
Those are a pair of 'supplementary' angles.
Yes (supposing that by side you mean ray...angles don't have sides because they are 2D, not 3D.) If you have a point and you draw four random rays from that point, that only meat at that point, then you would have created four angles. The two angles on opposite sides of the point will share a vertex, but not a RAY.
Alternate angles
That would be a right angle: The measure of complementary angles adds up to 90 degrees. Adjacent angles are angles that share one common side and one common vertex, but no common interior points (the angles don't overlap). The non-common sides of two adjacent angles are the two "outside" sides (the unshared sides). Two adjacent and complementary angles would form a right angle split by a ray/line, and not necessarily bisected (perfectly divided in half).
Adjacent angles have a shared vertex.
It is a vertex.
4 sides, 4 angles
It's important to remember that adjacent angles must have BOTH a common side and common vertex
The vertex.
Because it doesn't have sides,angles, or vertex's.
A shape with ten sides and seven vertex is impossible. There must always be the same amount of sides as vertex in a shape.
