What are the theorems of a parallelogram?
Space and AstronomyTheorems on Parallelograms Theorem1: A diagonal of a parallelogram divides it into two congruent triangles. Theorem 2: In a parallelogram, opposite sides are equal. Theorem 3: In a parallelogram, opposite angles are equal. Theorem 4: The diagonals of a parallelogram bisect each other. Q. How many theorems are there in parallelogram? You have now proven
How does a small star die?
Space and AstronomyStars die because they exhaust their nuclear fuel. The events at the end of a star’s life depend on its mass. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. What happens when a small star dies? After puffing off its outer
What is a closed system perspective?
Space and AstronomyThe closed-system perspective basically views an organization much as a thermostat; limited environmental input outside of changes in temperature is required for effective operation. Once set, thermostats require little maintenance in their ongoing, self-reinforcing function. What is the meaning of closed system? Open and Closed Systems A system can be either closed or open: A
What is a quadrilateral with two pairs of parallel sides called?

The atmosphere traps the small amount of energy from the sun that does reach the surface along with the heat the planet itself releases. Is there oxygen on Venus? Without life there is no oxygen; Venus is a bit closer to the
What is the Galilean telescope?
Space and AstronomyGalilean telescope, instrument for viewing distant objects, named after the great Italian scientist Galileo Galilei (1564–1642), who first constructed one in 1609. With it, he discovered Jupiter’s four largest satellites, spots on the Sun, phases of Venus, and hills and valleys on the Moon. How the Galilean telescope works? In Galileo’s version, light entering the
How do you find the reference angle on a calculator?
Space and AstronomyChoose the proper formula for calculating the reference angle: 0° to 90°: reference angle = angle , 90° to 180°: reference angle = 180° – angle , 180° to 270°: reference angle = angle – 180° , 270° to 360°: reference angle = 360° – angle . How do you find the reference angle on
What are quantities on a graph?
Space and AstronomyThe quantity that depends on the other quantity is called the dependent variable, and the quantity it depends on is called the independent variable. The values of variables are used in tables and in plotting graphs. In this lesson, we identify the dependent variable and the independent variable in a table or a graph. What
