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.
An acute angle is an angle with a measure between 0 and 90 degrees. An obtuse angle is an angle with a measure between 90 and 180 degrees. Two angles are complementary if the sum of their measures is equal to 90 degrees. Example: angles a and b with measures a = 19 and b = 71 are complementary since a + b = 90.
