Tall fescue (Lolium arundinaceum) seeds germinate in seven to 12 days. Hard fescue (Festuca longifolia) and red fescue (Festuca rubra) seeds take seven to 14 days. Plant 7 to 9 pounds of annual ryegrass seed or 6 to 9 pounds of perennial ryegrass per 1,000 square feet in the fall.
More About Base Angle Theorem. 1  Base angles of an isosceles triangle are equal.  Converse of the base angle theorem is also true, i.e. if two angles of a triangle are congruent, the sides opposite to these angles are congruent.
Right angle: When the angle measure exactly 90o, then the angle is called a right angle or we call that the two arms are perpendicular to one another.4. Obtuse angle: When the measure of the angle is more than 90o and less than 180o, then the angle is called an obtuse angle. Example: 91o, 100o, 179o 5.Straight angle: When the angle measure exactly 180o, then the angle is called a straight angle. 6.btuse angle: When the measure of the angle is more than 90o and less than 180o, then the angle is called an obtuse angle.
