Is a parabola a conic section?
Space and AstronomyThe parabola is another commonly known conic section. The geometric definition of a parabola is the locus of all points such that they are equidistant from a point, known as the focus, and a straight line, called the directrix. In other words the eccentricity of a parabola is equal to 1. Is parabola and conic

What are the Van Hiele levels of geometric understanding?
Space and AstronomyAbstract. The van Hiele theory describes how young people learn geometry. It postulates five levels of geometric thinking which are labeled visualization, analysis, abstraction, formal deduction and rigor. What are the instructional learning phases of van Hiele? To address these issues, the van Hieles proposed five sequential phases of learning: inquiry, directed orientation, explication, free

What does combine like terms mean?
Space and AstronomyLike Terms: Terms that have identical variable parts (same variable(s) and same exponent(s)). When simplifying using addition and subtraction, you combine “like terms” by keeping the “like term” and adding or subtracting the numerical coefficients. Examples: 3x + 4x = 7x. What is an example of combine like terms? A common technique for simplifying algebraic

What is the difference between a Protoplanet and a planet?
Space and AstronomyProtoplanet: A Protoplanet is basically a planet (Dwarf or normal) in the making. The difference is that a Protoplanet doesn’t have an almost spherical shape due to insufficient gravity which relates to its size. Is a protoplanet bigger than a planet? Protoplanets are small celestial objects that are the size of a moon or a

Is sqrt 7 a real number?
Space and AstronomyWhy is the Square Root of 7 an Irrational Number? The number 7 is prime. This implies that the number 7 is without its pair and is not in the power of 2. Therefore, the square root of 7 is irrational. Is root 7 a real number? So 7 divides p and p and p

What are angle properties?
Space and AstronomyThe angle properties of lines are: Vertically opposite angles are equal, for example a = d, b = c. Adjacent angles add to 180o, for example a + b = 180o, a + c = 180. o. Corresponding angles are equal, for example a = e, b = f, c = g, d= h. What
