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.

Geometric figures...

• Cone: A shape with a circular base and a single lateral face that narrowsto a vertex.
• Pyramid: It has a polygonal base and all its lateral faces are triangles that converge at a common vertex.
• Hemisphere: Half of a sphere, obtained by dividing it with a plane that passes through its center.

• Cube: A shape with 6 equal square faces, 12 edges, and 8 vertices. All its angles are right angles.
• Sphere: A round and perfectly symmetrical shape, with noedges or vertices.
• Cylinder: It has two circular bases and a curved lateral face thatconnects them.

About Muscles ..

• Involuntary muscles are muscles which are not under our conscious control.
• Voluntary muscles are muscles which are under our conscious control, so we can move these muscles when we choose to.
• Smooth muscle –an involuntary muscle found in the internal organs and blood vessels
• Cardiac muscle – an involuntary muscle found only in the heart
• Skeletal muscle – a voluntary muscle attached to the skeleton
