The vertex of the angle.
VerTex
vertex
Draw two line segments, AB and BC, meeting at a right angle at the point B. Pick any point, D, in the plane, which is inside angle ABC or its opposite angle. Join CD and AD. Then ABCD will be a quadrangle which meets the requirements.
angle B angle Y (Tested, correct) Nicki is not the answer, just ignore that.
Angle "A" is congruent to Angle "D"

Yes, so as long as the angle being identified (in this case, angle b) is in the center.
The vertex of an angle is the point where the two rays meet. An example is angle ABC. the two rays are ray BA and ray BC. The two rays meet at point B.
two lines intersect at point b which is also end point of two rays
The vertex is b and the rays are ba and bc.
vertex
'a' and 'b' must both be acute, complementary angles.
