What is a directed line segment?
Space and AstronomyDirected Line SegmentA directed line segment is a portion of a line that has both a magnitude and direction. MagnitudeThe magnitude of a line segment or vector is the length of the line segment or vector. VectorA vector is a mathematical quantity that has both a magnitude and a direction. How do you find the
How do you cut thick cork sheets?
Space and AstronomyIf you have thicker cork, like the kind you find in a bulletin board, the easiest way to cut it is with a utility knife. The pen-shaped thinner knives are usually best, but you can use a bigger box cutter-style utility knife if the cork is really bulky. How do you cut cork sheets? Use
Is Asa a similarity postulate?
Space and AstronomyDoes ASA prove similarity? Two triangles are similar if and only if the corresponding sides are in proportion and the corresponding angles are congruent. Just as there are specific methods for proving triangles congruent (SSS, ASA, SAS, AAS and HL), there are also specific methods that will prove triangles similar. What is ASA similarity theorem?
What is angular measure?
Space and AstronomyWhat is meant by angular measure? In geometry, an angle measure can be defined as the measure of the angle formed by the two rays or arms at a common vertex. Angles are measured in degrees ( °), using a protractor. Fun Facts. The protractor was invented by Joseph Huddart in 1801. It was a
What is Circle practice?
Space and AstronomyA circle is a versatile restorative practice that can be used proactively, to develop relationships and build community or reactively, to respond to wrongdoing, conflicts and problems. Circles give people an opportunity to speak and listen to one another in an atmosphere of safety, decorum and equality. What is circle teaching? Pat Hutchings, in her
How do the coma and tail of a comet form?
Space and AstronomyThe streams of dust and gas thus released form a huge, extremely tenuous atmosphere around the comet called the coma, and the force exerted on the coma by the Sun’s radiation pressure and solar wind cause an enormous tail to form, which points away from the Sun. How do the coma and tail of a

How do you know if an angle is Quadrantal?
Space and AstronomyWhich angle is Quadrantal angle? Definition A quadrantal angle is an angle in standard position whose terminal ray lies along one of the axes. Examples of quadrantal angles include, 0, π/2 , π , and 3π/ 2. Angles coterminal with these angles are, of course, also quadrantal. What does it mean if an angle is
How do you find the equation of a circle by completing the square?
Space and AstronomyRemember that the circle formula is (x – h)2 + (y – k)2 = r2. If you end up with an equation like (x + 4)2 + (y + 5)2 = 5, you have to keep straight that h and k are subtracted in the center-radius form, so you really have (x – (–4))2 +
What are roots in Algebra 2?
Space and AstronomyThe solutions to y = f (x) when y = 0 are called the roots of a function (f (x) is any function). These are the points at which the graph of an equation crosses the x-axis. How do you find the zeros and roots of a polynomial function? We say that x=r is a
