What is an example of one to one correspondence?
Space and Astronomy1 to 1 correspondence is the skill of counting one object as you say one number. For example, if you are counting objects, you point at the first item and say ‘1’, then point to the second and say ‘2’ and so on. Sounds simple! Which of the following is an example of one-to-one correspondence?

How do you find the postulate?
Space and AstronomyIf you have a line segment with endpoints A and B, and point C is between points A and B, then AC + CB = AB. The Angle Addition Postulate: This postulates states that if you divide one angle into two smaller angles, then the sum of those two angles must be equal to the

What is the difference between total and annular eclipse?
Space and AstronomySolar eclipses may be classified as either total, in which the Moon completely covers the Sun, or annular, in which the Moon obscures all but an outer ring of the Sun. Whether an eclipse is total or annular depends on the distance between these three objects. What is the difference between a total solar eclipse

Are two vertical angles complementary?
Space and AstronomyVertical angles have equal measures. Therefore, if vertical angles measure 45o each, they are complementary. Is vertical angles supplementary or complementary? Lesson Summary You learned that complementary angles are two angles that add up to 90 degrees, supplementary angles are two angles that add up to 180 degrees, vertical angles are opposite angles at an

What is the cast rule?
Space and AstronomyThe CAST Rule. The CAST Rule says that in quadrant I all three of sinθ, cosθ, tanθ are positive. In quadrant II, only sinθ is positive, while cosθ, tanθ are negative. In quadrant III, only tanθ is positive, while sinθ, cosθ are negative. How do you
