Each part that is split becomes a separate worm, and they reproduce asexually when it splits. It makes them reproduce asexually. They have a cocoon that carries eggs, swells in their body then, releases the cocoon, and attach it to water weeds. The cocoon has yolk, which nourishes the eggs. The eggs are then hatched.
A line segment is a part of a line having two endpoints. A ray is a part of a line with one endpoint and goes on and on in one direction... Parallel lines are lines that never intersect or cross one another. Perpendicular lines cross each other or intersect at right angles. An angle is two lines that meet at an endpoint called a vertex. An angle can be named by the three letters that form it or by the letter that is at its vertex. An acute angle is one that measures less than 90 degrees with a protractor-that is how much the angle is open or the lines diverge from the vertex.
In a right triangle, the orthocenter is the polygon vertex of the right angle. When the vertices of a triangle are combined with its orthocenter, any one of the points is the orthocenter of the other three, as first noted by Carnot (Wells 1991). These four points therefore form an orthocentric system. The circumcenter and orthocenter are isogonal conjugates. The orthocenter lies on the Euler line.
