The vertex of the angle.
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"
The vertex of the angle.
vertex
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
Are you talking about the angle A. If you are then at what point of the triangle is the angle A.
The vertex is b and the rays are ba and bc.
Yes, so as long as the angle being identified (in this case, angle b) is in the center.
'a' and 'b' must both be acute, complementary angles.
