Geometric Figures

The flat geometric figures have only two dimensions: length and width. These figures have no height and are found in a plane.

Square

Hexagon

Pentagon

The squareis a flat figure with fourequal sidesand four right angles.

The pentagonis a flat figure with five sides andfive angles.

The hexagonis a flat figure with six sides andsix angles.

The cubeis a solid with six square faces, all equal, andeight vertices.

The cylinderis a solid with two equal circular bases joined by a curved surface.

3D geometric figures

Solid figures have three dimensions: length, width, and height. Unlike flat figures, these occupy spaceand have volume

The hemisphere is half of a sphere, divided by a plane that passes throughits center.

The pyramidis a solid with a polygonal base and triangular faces that meet ata vertex.

Sphere

Hemisphere

Pyramid

The sphereis a perfect solid, with all its points equidistant from a center.

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 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.
