When working with vectors, you will often see right triangles. what are the consistent properties of these triangles? (choose all that apply.) when working with vectors, you will often see right triangles. what are the consistent properties of these triangles?
a. the triangles are always equilateral.
b. the sides of the triangles always line up with the x- and y-axes.
c. the hypotenuse of the triangle is always the vector itself.
d. the triangles always have the same base and height.

100 ! make you brainliest! asap pleaze hurry 1. which scientific theory explains that the universe originated from a small, densely packed space? 2. observations of space show that galaxies are moving away from us as observers on earth. how is this related to how the universe formed? 3. one force is responsible for holding together stars with planets, planets with moons, and stars in galaxies. what is this force? 4. as the solar system formed, most of its mass became concentrated in one part of it. what is that that part? 5. using the law of gravitation, explain why the moon orbits the earth and the planets orbit the sun. 6. many people think that summer is warmer because the earth is closer to the sun at that time of year. your experience with seasons has taught you this is not true. explain why. 7. if earth rotated on an axis that was not tilted, how would this affect the seasons? 8. does this show the geocentric or heliocentric idea of the solar system? explain the difference. 10. as fast as you can, name the planets in order from the sun. 11. as fast as you can, name the planets in order from smallest to largest. 12. as fast as you can, name the planets in order from least mass to most mass. hint: check your notes about the gravitational force on each planet compared with earth. name a unique trait about each planet in our solar system.
