4. Triangle A triangle has three sides. To find the area of the triangle you use this formula -1/2bh *the b stands for base and the h stands for height The Pythagorean theorem helps to find missing angle or side of a right triangle The Pythagorean theorem is: a 2 + b 2 = c 2 Click on the button to go back to the main menu!

5. Square A square has four equal sides and angles. To find the area of the square use the formula: area = s 2 To find the perimeter of the square use this formula: perimeter = 4s Click on the button to go back to the main menu!

6. Rectangle A rectangle has four sides. To find the area of a rectangle use this formula: Area= length * width To find the perimeter of a rectangle use this formula: perimeter=2length*2width Click on the button to go back to the main menu!

7. Rhombus A rhombus has four sides that are the same length. To find the area of a rhombus use this formula: area= base * height To find the perimeter of a rhombus use this formula: Perimeter=4S(S= sides) Click on the button to go back to the main menu!

8. Parallelogram A parallelogram has four sides that are parallel. To find the area of a parallelogram use this formula: Area= base *height To find the perimeter of a parallelogram use this formula: perimeter=2(base *Side) Click on the button to go back to the main menu!

9. Circle A circle has no sides. To find the area of a circle use this formula: Area= PI r 2 To find the perimeter of a circle use this formula perimeter =PI x diameter or 2PI *radius. The perimeter of a circle is also known as the circumference. Click here to go back to the main menu!

10. Pentagon A pentagon has five sides. To find the area of a pentagon use this formula: Area= S2N/4tan (PI/N)] – S= sides – N= number of sides To find the perimeter of a pentagon use this formula Perimeter = 5*length of the sides. Click here to go back to the main menu!

11. Hexagon A hexagon has six sides. To find the area of a hexagon use this formula: Area =(3√3/2 )r 2 To find the perimeter of a hexagon use this formula: Perimeter =6r Click here to go back to the main menu!
