Study Notes

Quadrilaterals

Quadrilateral: A polygon with four sides.
Trapezoid: A quadrilateral featuring a single pair of parallel sides.
Parallelogram: Characterized by having two pairs of parallel sides.
Rhombus: A special quadrilateral with all sides of equal length, lacking right angles.
Square: A quadrilateral where all sides are equal and each angle measures 90 degrees.
Rectangle: A quadrilateral that has four right angles, with sides not necessarily of equal length.

Triangles

Right Triangle: Defined by the presence of one angle measuring exactly 90 degrees.
Acute Triangle: Contains only angles that are smaller than 90 degrees.
Obtuse Triangle: Features one angle that exceeds 90 degrees.
Equilateral Triangle: All three sides are congruent, with equal lengths.
Isosceles Triangle: Has two sides that are equal in length.
Scalene Triangle: Distinguished by having no sides of equal length.
