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.
If the left angle measures 145 degrees, then the angle that is opposite it also measures 145 degrees. Another property of vertical angles is that angles that are next to each other are supplementary angles, meaning that they add up to 180 degrees. So, if one angle measures 35 degrees, then the angle that is directly to the left or right will measure 145 degrees, since 35 + 145 is 180. Using Vertical Angles. To use the identifying property of vertical angles, you just need to know the measurement of the angle that is opposite the angle that is missing the measurement. So, if your missing angle is the bottom angle, all you need to know is the measurement of the top angle. If the top angle measures 60, then so does the bottom angle.
