Based on the information available, all that can be said is that it is a (not an) right angle with vertex k. Nothing more!
Same as it is in any other angle ... the point where the sides of the angle join (or cross).
When the triangle is right, the orthocenter is the polygon vertex of the right angle. Intuitively this makes sense because the orthocenter is where the altitudes intersect. Hence, in a right triangle, the vertex of the right angle is where you would expect the altitudes to meet, at 90 degrees, where the legs of the right triangle are perpendicular.
Simply by measuring it. Or by drawing a circle with a radius of half the hypotenuse and having the vertex of the right angle as its centre and if the midpoint of the hypotenuse just touches the circle then this proves it.
Acute: 0 < X < 90; Right: = 90; Obtuse: 90 < X < 180; Straight: = 180; Reflex: 180 < X < 360. The Acut, Right, Straight and Reflex are actually classifications of an angle. Naming of an angle is done by identifying the vertex and a combination of the vertex and points on the two rays. For example an angle with points ABC where B is the vertex and A and C are points on the accompanying rays may be named as angle B, angle ABC or angle CBA. These can be written with the symbol for angle placed before the B the ABC and the CBA.
Draw an angle that is larger than a right angle label the vertex k
not sure how

At the vertex of the right angle.
Yes, as long as the label for the vertex stays in the middle, you can read it in any direction you want.
You use the points of the vertex and on the two sides. For example a right angle with a vertex of A and two sides B and C. would be Angle BAC
a right angle
Right angle E. The vertex of any angle can also be used to name the angle.
Same as it is in any other angle ... the point where the sides of the angle join (or cross).
at the vertex i think
A right angle joint is called a vertex as is with any other angle (yes even straight angles)
The hypotenuse of a right angle triangle is opposite to its right angle of 90 degrees.
