How to render a Bounding Box over a rotating Box - c++

Question

Hello Im new to C++ SFML. I would like to ask how I would go about rendering a bounding box over a rotating box. The way I did this was by making another rectangle that was transparent but with outlines and got it to getGlobalBounds of the rotating rectangle but it isn't rendering quite right because I've been using setSize to get the bounding box to grow which means the upper and left portion of the box isnt resizing. I feel like i'm missing something here so Here's my code:
sf::RectangleShape Rect[RECT];
sf::RectangleShape AABB[RECT];
Rect[0].setSize(sf::Vector2f(50.0f, 50.0f));
Rect[1].setSize(sf::Vector2f(50.0f, 100.0f));
Rect[2].setSize(sf::Vector2f(60.0f, 80.0f));
Rect[3].setSize(sf::Vector2f(100.0f, 60.0f));
Rect[4].setSize(sf::Vector2f(30.0f, 250.0f));
AABB[0].setSize(sf::Vector2f(50.0f, 50.0f));
AABB[1].setSize(sf::Vector2f(50.0f, 100.0f));
AABB[2].setSize(sf::Vector2f(60.0f, 80.0f));
AABB[3].setSize(sf::Vector2f(100.0f, 60.0f));
AABB[4].setSize(sf::Vector2f(30.0f, 250.0f));
for (int x = 0; x < RECT; x++)
{
//Starting Position
Rect[x].setOrigin(Rect[x].getSize().x / 2, Rect[x].getSize().y / 2);
AABB[x].setOrigin(AABB[x].getSize().x / 2, AABB[x].getSize().y / 2);
xpos += 150;
Rect[x].setPosition(xpos, ypos);
AABB[x].setPosition(xpos, ypos);
colcount++;
if (colcount == 3)
{
xpos = 0;
ypos += 200;
colcount = 0;
}
Rect[x].setFillColor(sf::Color::Red);
AABB[x].setFillColor(sf::Color::Transparent);
AABB[x].setOutlineThickness(1);
}
while (window.isOpen())
{
window.clear(sf::Color::Black);
//Drawing Shapes
for (int x = 0; x < RECT; x++)
{
window.draw(Rect[x]);
window.draw(AABB[x]);
}
Rect[0].rotate(90 * 3.14 / 180);
Rect[1].rotate(45 * 3.14 / 180);
Rect[2].rotate(10 * 3.14 / 180);
Rect[3].rotate(180 * 3.14 / 180);
Rect[4].rotate(22.5);
for (int i = 0; i < RECT; i++)
{
MinPoint[i].x = Rect[i].getPosition().x - (Rect[i].getSize().x / 2);
MaxPoint[i].x = Rect[i].getPosition().x + (Rect[i].getSize().x / 2);
MinPoint[i].y = Rect[i].getPosition().y - (Rect[i].getSize().y / 2);
MaxPoint[i].y = Rect[i].getPosition().y + (Rect[i].getSize().y / 2);
AABB[i].setSize(sf::Vector2f(Rect[i].getGlobalBounds().width, Rect[i].getGlobalBounds().height));
}

I finally got it to work. Here's what I did:
sf::RectangleShape Rect[RECT];
sf::RectangleShape AABB[RECT];
Rect[0].setSize(sf::Vector2f(50.0f, 50.0f));
Rect[1].setSize(sf::Vector2f(50.0f, 100.0f));
Rect[2].setSize(sf::Vector2f(60.0f, 80.0f));
Rect[3].setSize(sf::Vector2f(100.0f, 60.0f));
Rect[4].setSize(sf::Vector2f(30.0f, 250.0f));
for (int x = 0; x < RECT; x++)
{
//Starting Position
Rect[x].setOrigin(Rect[x].getSize().x / 2, Rect[x].getSize().y / 2);
AABB[x].setOrigin(AABB[x].getSize().x / 2, AABB[x].getSize().y / 2);
xpos += 150;
Rect[x].setPosition(xpos, ypos);
AABB[x].setSize(sf::Vector2f(Rect[x].getGlobalBounds().width, Rect[x].getGlobalBounds().height));
AABB[x].setPosition(Rect[x].getPosition().x, Rect[x].getPosition().y);
colcount++;
if (colcount == 3)
{
xpos = 0;
ypos += 200;
colcount = 0;
}
Rect[x].setFillColor(sf::Color::Red);
AABB[x].setFillColor(sf::Color::Transparent);
AABB[x].setOutlineThickness(1);
AABB[x].setOutlineColor(sf::Color::White);
}
while (window.isOpen())
{
window.clear(sf::Color::Black);
//Drawing Shapes
for (int x = 0; x < RECT; x++)
{
window.draw(Rect[x]);
window.draw(AABB[x]);
}
//Rotation
Rect[0].rotate(1);
Rect[1].rotate(45);
Rect[2].rotate(11.25);
Rect[3].rotate(5.625);
Rect[4].rotate(22.5);
for (int i = 0; i < RECT; i++)
{
MinPoint[i].x = AABB[i].getPosition().x - (AABB[i].getSize().x / 2);
MaxPoint[i].x = AABB[i].getPosition().x + (AABB[i].getSize().x / 2);
MinPoint[i].y = AABB[i].getPosition().y - (AABB[i].getSize().y / 2);
MaxPoint[i].y = AABB[i].getPosition().y + (AABB[i].getSize().y / 2);
AABB[i].setOrigin(AABB[i].getSize().x / 2, AABB[i].getSize().y / 2);
AABB[i].setSize(sf::Vector2f(Rect[i].getGlobalBounds().width, Rect[i].getGlobalBounds().height));
AABB[i].setPosition(Rect[i].getPosition().x, Rect[i].getPosition().y);
}
