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.
If two angles are complements of the same angle (or of congruent angles), then the two angles are congruent. Congruent Supplements Theorem If two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent. Right Angles Theorem. All right angles are congruent. Same-Side Interior Angles Theorem. If a transversal intersects two parallel lines, then the interior angles on the same side of the transversal are supplementary. Converse also true: If a transversal intersects two lines and the interior angles on the same side of the transversal are supplementary, then the lines are parallel. The sum of the degree measures of the same-side interior angles is 180Â°.
