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.
Right Angle. A right angle is an angle whose measure is exactly 90Â°. An easy way to determine whether an angle is a right angle is by considering whether a small square could fit perfectly in the corner of the intersection of the two lines that form the angle.
