  1. 1. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Perimeter and Area Matem´ticas 1o E.S.O. a Alberto Pardo Milan´s e -
  2. 2. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises 1 Definitions 2 Triangles 3 Quadrilaterals 4 Regular polygons 5 Circles 6 Exercises
  3. 3. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises DefinitionsAlberto Pardo Milan´s e Perimeter and Area
  4. 4. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Definitions Perimeter and Area The perimeter of a surface is the length of this boundary. The area of a surface is the amount of material needed to cover it completely.Alberto Pardo Milan´s e Perimeter and Area
  5. 5. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises TrianglesAlberto Pardo Milan´s e Perimeter and Area
  6. 6. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Triangles Area of a triangle The area of a triangle can be found by multiplying the base times the one-half the height.Alberto Pardo Milan´s e Perimeter and Area
  7. 7. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises QuadrilateralsAlberto Pardo Milan´s e Perimeter and Area
  8. 8. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Quadrilaterals Area and Perimeter of a Square The perimeter of a square is the distance around the outside of the square. A square has four sides of equal length. The formula for finding the perimeter of a square is 4 times the length of a side. The area of a square can be found by multiplying the length of a side times itself.Alberto Pardo Milan´s e Perimeter and Area
  9. 9. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Quadrilaterals Area and Perimeter of a Rectangle A rectangle has four sides and four right angles. The formula for finding the perimeter is 2 times the base plus 2 times the height. The area of a rectangle can be found by multiplying the base times the height.Alberto Pardo Milan´s e Perimeter and Area
  10. 10. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Quadrilaterals Area and Perimeter of a Parallelogram Parallelograms are quadrilaterals with opposite sides parallel (two pairs of sides parallel). In a parallelogram opposite sides are congruent (with the same length). The formula for finding the perimeter is 2·Side a + 2·Side b. The area of a parallelogram can be found by multiplying the base times the height.Alberto Pardo Milan´s e Perimeter and Area
  11. 11. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Quadrilaterals Area of a Trapeziums A trapezium is a quadrilateral (has 4 sides) and has only one pair of sides parallel. To determine the area of a trapezoid, first add the lengths of the 2 parallel sides, then divide by 2, finally multiply this by the height (distance between the parallel sides).Alberto Pardo Milan´s e Perimeter and Area
  12. 12. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Regular polygonsAlberto Pardo Milan´s e Perimeter and Area
  13. 13. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Regular polygons Area and Perimeter of a Regular Polygon The perimeter of regular polygon with n sides is n times the lenght of a side. The area of a regular polygon is the one-half the apothem times the perimeter.Alberto Pardo Milan´s e Perimeter and Area
  14. 14. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises CirclesAlberto Pardo Milan´s e Perimeter and Area
  15. 15. Indice Definitions Triangles Quadrilaterals Regular polygons Circles Exercises Circles Area and Circumference of a Circle The circumference of a circle is the distance around the outside of the circle. It could be called the perimeter of the circle. The circumference of a circle can be found by multiplying π by the diameter of the circle. If you know the radius, the diameter is twice as large. The area of a circle can be found by multiplying π by the square of the radius.Alberto Pardo Milan´s e Perimeter and Area
