No at least i dont think so!
Yes.
flatangle (apex) A straight angle.
180 degree angle.
180 degrees lie on a straight line
Three or more points are collinear if they lie on the same straight line.Three or more points are collinear if they lie on the same straight line.Three or more points are collinear if they lie on the same straight line.Three or more points are collinear if they lie on the same straight line.
Collinear lines lie on the same straight line
No, an angle is not a polygon - lie a triangle - which is a closed plane shape bounded by straight lines.
A zero angle is a straight positive line. The x coordinate is positive and y is zero. In addition, zero angle is a coterminal of 360 degree angle meaning that they lie in the same position.zero angle.------------------>An angle whose measure is 0 degrees is called zero angle.
Points that lie on the same line
If a point lies on a segment whose endpoints are on the sides of an angle but is not an endpoint of the segment, then it is located strictly between the two endpoints of that segment. This means the point is inside the angle formed by the two sides, but not on the angle's boundary itself. The point divides the segment into two smaller segments, both of which lie within the angle.
Collinear lines lie on the same straight line.
No. In fact, if you make a triangle with sides of 17, 20, and 37, anybody who sees it thinks that it's just a piece of straight line. The 17 and the 20 lie down along the 37. The triangle is "degenerate" ... two of its angles are zero, and the third angle is 180 degrees, and two of its sides lie on top of the third side.
