Understanding Arrowhead Quadrilaterals

Characteristics and Properties

An arrowhead quadrilateral is a geometric shape with distinct characteristics and properties:

  • It has four sides and four angles.
  • Two opposite angles are greater than 180 degrees, resembling the shape of an arrowhead.
  • The other two angles are acute (less than 90 degrees).
  • The sum of all interior angles is 360 degrees.
  • It may have different side lengths and angle measures.

Types of Arrowhead Quadrilaterals

There are several types of arrowhead quadrilaterals based on their specific configurations:

  • Acute Arrowhead Quadrilateral: All angles are acute.
  • Obtuse Arrowhead Quadrilateral: One angle is obtuse, and the other three are acute.
  • Right Arrowhead Quadrilateral: One angle is a right angle (90 degrees), and the other three are acute.
  • Irregular Arrowhead Quadrilateral: No specific angle configurations, but still satisfies the definition of an arrowhead quadrilateral.
