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.
An equilateral triangle has three sides of equal length and three equal angles. An isosceles triangle has two sides of equal length and two equal angles. A scalene triangle has no sides of equal length and no equal angles. A right angle triangle has one angle that is 90 degrees.An obtuse triangle has one angle larger than 90 degrees. An acute triangle has angles that are all less than 90 degrees.The longest side of a right angle triangle is called the hypotenuse, it is always found opposite the right angle.Trigonometry is the study of the relationship between the angles of triangles and their sides. Triangle shapes are often used in construction because of their great strength.he longest side of a right angle triangle is called the hypotenuse, it is always found opposite the right angle.
