# Quadrilateral problems on the coordinate plane

CCSS.Math:

Try five problems involving quadrilaterals on the coordinate plane.

## Problem 1: Find coordinates of missing vertex

## Problem 2: Area of parallelogram on coordinate plane

## Problem 3: Dimensions of rectangle from coordinates

## Problem 4: Coordinates of rectangle

## Bonus problem: Parallelogram on the coordinate plane

- 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.(10 votes)

- why is the alphabet now on math(7 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.(7 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)

- 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)

- Im so confused.(3 votes)
- I need help with problem 2 pls :((2 votes)
- This is a three-step problem.

Step 1: Count how many lines between the top left and the bottom left points. This will give you the length of the shape.

Step 2: Draw a line from the bottom right point down to the coordinate (6,-7). Label (6,-7) point X. The distance from the bottom-left point to point X is the perpendicular height.

Step three: Multiply the answers to step 1 and step 2 together. This will give you your total.(2 votes)

- what is a coordinate grid used for because im really confussed(2 votes)
- The Coordinate grid is used to easily show distance without having to label lengths(1 vote)
