MTH208B Graded Assignment Unit 2 Test Part 2: Relationships of Two- and Three-D (Score for Question 3: ___ of 5 points) 3. Quadrilateral EFGH has vertices at E(10, 4), F(16, 4), G(16, 10) and H(10, 10). Based on the properties of the diagonals, is quadrilateral EFGH a rectangle, rhombus, or square? Use the distance and slope formulas to prove your conclusion. Show your work. ​

there is no grid

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
