The 3rd angle of the triangle could be 90 degrees because the 3 angles in a triangle add up to 180 degrees.
the letter C lies on top, the first point of the angle. A is the "vertex" it connects both lines to form an angle the bottom could be letter B. "<" that's an angle. B and C could never be on the Vertex.
A rhombus, trapezoid or parallelogram could all contain a 45 degree vertex. Squares and rectangles only have 90 degree vertices.
trapezoid, parallelogram, and rhombus (people call it the diamond)
a right angle is 90 degrees a straight angle is 180 degrees you could also use a anglicize
A quadrilateral that could have a 45-degree vertex angle is a kite. In a kite, the two pairs of adjacent sides are congruent, and one pair of opposite angles is congruent. Therefore, if one of the angles is 45 degrees, the opposite angle would also be 45 degrees. This makes a kite one of the quadrilaterals that could have a 45-degree vertex angle.

It could be called angle C, as long as that name is unambiguous.
To draw an angle of 174 degrees, you can follow these steps: Draw a straight line using a ruler or straightedge. This will be one side of the angle. At one end of the line, use a compass to draw an arc of 174 degrees, making sure that the arc intersects the line you drew in step 1. Without changing the width of the compass, place the point of the compass at the other end of the line you drew in step 1, and draw another arc that intersects the first arc you drew in step 2. Draw a line connecting the endpoint of the line and the intersection point of the two arcs, creating the second side of the angle. Label the vertex of the angle with a capital letter. To name the angle, you can use the vertex letter and the endpoint letters, in that order, with the vertex letter in the middle. In this case, the angle could be named "angle BAC" or "angle CAB", depending on which endpoint you choose to name first. As for the type of angle, an angle of 174 degrees is an obtuse angle because it measures greater than 90 degrees but less than 180 degrees.
So you could measure the angle.
Well it could be complementary or supplementary because they don't have to share a vertex yet I think you mean something like the vertical angle. You can go research vertical angles. I'll give you a link for the vertical angles. http://www.mathsisfun.com/geometry/vertical-angles.html

An obtuse angle

It could be an obtuse angle, and it could be a reflex angle.
