**Vertices of rectangle question8 :**

Here we are going to see practice question on vertices of parallelogram.

**Definition of rectangle :**

A rectangle is a quadrilateral in which opposite sides are parallel and equal in length. In other words opposite sides of a quadrilateral are equal in length then the quadrilateral is called a rectangle.

**Question 8 :**

Examine whether the given points A (2,-2) and B (8,4) and C (5,7) and D (-1,1) forms a rectangle.

**Solution :**

To show that the given points forms a rectangle we need to find the distance between three points.

Distance Between Two Points (x ₁, y₁) and (x₂ , y₂)

**√(x₂ - x₁)² + (y₂ - y₁)²**

Four points are A (2,-2) and B (8,4) and C (5,7) and D (-1,1)

Distance between the points A and B

= **√(x₂ - x₁)² + (y₂ - y₁)²**

Here **x₁ = 2, y₁ = -2, x₂ = 8 and y₂ = 4**

**= **
√(8-2)² + (4-(-2))²

= ** **
√(6)² + (4+2)²

= ** **
√6² + (6)²

= √36 + 36

= √72 units

Distance between the points B and C

= **√(x₂ - x₁)² + (y₂ - y₁)²**

Here **x₁ = 8, y₁ = 4, x₂ = 5 and y₂ = 7**

**= **
√(5-8)² + (7-4)²

= ** **
√(-3)² + (3)²

= ** **
√9 + 9

= √18

= √18 units

Distance between the points C and D

= **√(x₂ - x₁)² + (y₂ - y₁)²**

Here **x₁ = 5, y₁ = 7, x₂ = -1 and y₂ = 1**

**= **
√(-1-5)² + (1-7)²

= ** **
√(-6)² + (-6)²

= ** **
√36 + 36

= √72

Distance between the points D and A

**= √(x₂ - x₁)² + (y₂ - y₁)²**

Here **x₁ = -1, y₁ = 1, x₂ = 2 and y₂ = -2**

**= **
√(2-(-1))² + (-2-1)²

= ** **
√(2+1)² + (-3)²

= ** **
√3² + (-3)²

= √9 + 9

= √18 units

AB = √72 units

BC = √18 units

CD = √72 units

DA = √18 units

Length of opposite sides are equal.To test whether it forms right triangle we need to find the length of diagonal AC. vertices of rectangle question8

Distance between the points A and C

= **√(x₂ - x₁)² + (y₂ - y₁)²**

Here **x₁ = 2, y₁ = -2, x₂ = 5 and y₂ = 7**

**= **
√(5-2)² + (7-(-2))²

= ** **
√(3)² + (7+2)²

= ** **
√3² + 9²

= √9 + 81

= √90 units

AC² = AB² + BC²

(√90)² = (√72) ² + (√18)²

90 = 73 + 18

90 = 90

So the given vertices forms a rectangle.

(1) Examine whether the given points A (-3,2) and B (4,2) and C (4,-3) and D (-3,-3) forms a rectangle.

(2) Examine whether the given points A (8,3) and B (0,-1) and C (-2,3) and D (6,7) forms a rectangle.

(3) Examine whether the given points A (-2,7) and B (5,4) and C (-1,-10) and D (-8,-7) forms a rectangle.

(4) Examine whether the given points P (-3,0) and Q (1,-2) and R (5,6) and S (1,8) forms a rectangle.

(5) Examine whether the given points P (-1,1) and Q (0,0) and R (3,3) and S (2,4) forms a rectangle.

(6) Examine whether the given points P (5,4) and Q (7,4) and R (7,-3) and S (5,-3) forms a rectangle.

(7) Examine whether the given points P (0,-1) and Q (-2,3) and R (6,7) and S (8,3) forms a rectangle.

(8) Examine whether the given points A (2,-2) and B (8,4) and C (5,7) and D (-1,1) forms a rectangle.
