What angles are supplementary in a transversal?
Space & NavigationIf two parallel lines are cut by a transversal, then, interior angles on the same side of the transversal are supplementary. If two parallel lines are cut by a transversal, then, exterior angles on the same side of the transversal are supplementary. Which angle pairs are supplementary? Supplementary angles are two angles whose measures add

What is a geometric proof?
Space & NavigationGeometric proofs are given statements that prove a mathematical concept is true. In order for a proof to be proven true, it has to include multiple steps. These steps are made up of reasons and statements. How do you write a geometric proof? The Structure of a Proof Draw the figure that illustrates what is

Why are Cepheids used as standard candles?
Space & NavigationIt turns out that the rate at which the star pulsates is correlated with how bright the star is. If astronomers can measure the period of a Cepheid variable, they can calculate the absolute magnitude of the star, making Cepheid variables standard candles.Dec 6, 2015 Why can quasars be used as standard candles? Astronomers have

How far is from earth to moon?
Space & NavigationHow long does it take to reach the Moon? about 3 days It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen. How

What evidence supports the Big Bang theory?
Space & NavigationTwo major scientific discoveries provide strong support for the Big Bang theory: • Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed; and • the discovery in the 1960s of cosmic microwave background radiation. What are the 3 evidence of the big bang theory? Three key pieces

What is acyclic graph in data structure?
Space & NavigationAn acyclic graph is a graph without cycles (a cycle is a complete circuit). When following the graph from node to node, you will never visit the same node twice. This graph (the thick black line) is acyclic, as it has no cycles (complete circuits). A connected acyclic graph, like the one above, is called
