What is descriptive geometry in architecture?
Space & NavigationDescriptive geometry is a section of geometry in which different methods of three- dimensional representation of objects on a flat surface are studied. It is one of the main disciplines in professional training of an architect. What is the meaning of descriptive geometry? Definition of descriptive geometry : the theory of geometry treated by means
What are the properties of vertically opposite angles?
Space & NavigationThe point where they meet is called a vertex. When two lines intersect, the opposite (X) angles are equal. In the diagram above, the two green angles are equal and the two yellow angles are equal. These X angles are called vertically opposite angles because they are opposite each other at a vertex. What is
What is the difference between a star and a meteor?
Space & NavigationMeteors. If a meteoroid comes close enough to Earth and enters Earth’s atmosphere, it vaporizes and turns into a meteor: a streak of light in the sky. Because of their appearance, these streaks of light are sometimes called “shooting stars.” But meteors are not actually stars. Is a meteor considered a star? Video quote: It's
What is Apothem length of a hexagonal prism?
Space & NavigationSo, the apothem of a regular hexagon with 8-cm sides is about 6.93 cm. Where is the apothem in a hexagon? The apothem (sometimes abbreviated as apo) of a regular polygon is a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center
What does an optical interferometer measure?
Space & Navigationoptical interferometer, instrument for making precise measurements for beams of light of such factors as length, surface irregularities, and index of refraction. It divides a beam of light into a number of beams that travel unequal paths and whose intensities, when reunited, add or subtract (interfere with each other). What can an interferometer measure? Because
Where are asteroids hypothesized to have originated?
Space & NavigationAsteroids are thought to be leftovers from the formation of the solar system. Where are asteroids hypothesized to have originated? The Voyagers found new satellites and a thin ring around Jupiter. Where did asteroids originally come from? Asteroids are leftovers from the formation of our solar system about 4.6 billion years ago. Early on, the
