About angles...

  • They are formed when two lines meet ata point (vertex).
  • They are measured in degrees (°).
  • They indicate the opening between the lines.
  • They are fundamental in geometry and othermathematical areas.

Geometric figures...

  • Square: A quadrilateral with 4 equal sides and 4 right angles.
  • Pentagon: Five sides and five interior angles, and the total sum of the interior angles is 540 degrees.
  • Hexagon: Six sides and six interior angles, and the sum of its interior angles is 720 degrees.
  • Circle: A round figure where all points are at the same distance fromthe center.
  • Triangle: A figure with three sides. Types: equilateral (all sides equal), isosceles (two sides equal), and scalene (all sides different).
  • Rectangle: A quadrilateral with 4 right angles, but its opposite sides are of equal length.

About fractions...

They consist of two numbers: the numerator, which indicates how many parts we take, and the denominator, which tells us into how many parts the whole is divided. Fractions are fundamental in mathematics, as they allow us to work with divisions more precisely and understand concepts like proportions and decimals.
