Presentation Transcript


Acute angles measure between 0 o and 90 o

Acute Angles

measure between 0o and 90o


Acute angles measure between 0 o and 90 o

Right Angle

always measures 90o


Acute angles measure between 0 o and 90 o

  • Obtuse Angles

  • measures between 90o and 180o


Acute angles measure between 0 o and 90 o

  • Straight Angle

  • always measures 180°

  • ABC is a straight angle.


    Acute angles measure between 0 o and 90 o

    Complementary Angles

    angles whose measures have a sum of 90°

    DBE and EBC are complementary


    Acute angles measure between 0 o and 90 o

    Supplementary Angles

    angles whose measures have a sum of 180°

    mABD + mDBC = 124° + 56° = 180°


    Acute angles measure between 0 o and 90 o

    Adjacent Angles

    • Angles that share a common side and a common vertex.

    ABD is adjacent to DBC.
