- why is the alphabet now on math(14 votes)
- the letters aren't considered as the alphabet in the problems they are just used to show the different points and they also use the letters to name the points so that you don't get confused.(10 votes)

- how do you do the bonus problum?(9 votes)
- First, calculate the length of segment DC. X-axis of point D to C = -1.5 + s = 4.5 and y-axis of point D to C = 4+t=4. Then we got the length s is 6 and the length t is 0.

(Remember length in the segment is length between two-point. s and t is just a variable to represent the length in x-axis and y-axis of segment DC.)

Since the length of segment AB is the same as the length of segment DC---> X-axis of point A to B = 1 + 6 = j and Y-axis of point A to B = 1 + 0 = k ---> B(j , k) =B(7 , 1).

Sorry for my English. Hope this helps.(12 votes)

- How do you do this I don't understand the parraellograms(7 votes)
- To solve it easily, you first have to find the length of the base, or the long side. You also should find the height, and it is the distance from the long side to the other long side. After you find those dimensions, solve the rest like how you would solve for the area of an rectangle and square.(1 vote)

- Hey guys

I'm taking Geometry this coming fall, so I'm trying to prepare by taking the Khan courses, "Geometry" and "Get ready for Geometry." The course "Get ready for Geometry" is a bit easy right now, so I'm wondering if I should skip it and jump to the course "Geometry." What do you guys think? Is "Get ready for Geometry" vital for the course "Geometry"?(5 votes)- Sorry, I think I posted in the wrong section, so I'll repeat just in case: I think the "Get ready for Geometry" is pretty useful, but I don't think it's vital if you understand most of the concepts already.🙃(1 vote)

- I did a unit test and it did not test all of the skills inside that unit (6th Grade Geometry). Why weren't all of the skills tested as it was supposed to be a unit test?(3 votes)
- Sometimes, there are not enough questions in the Unit Test to level you up in all of the skills. You might have to take the Unit Test more than once to reach your mastery goal.(3 votes)
