    Study Notes

    Acute Triangle

    • Contains three acute angles, each less than 90 degrees.
    • Can be scalene if all sides have different lengths.

    Right Scalene Triangle

    • Features three unequal sides.
    • Each angle can vary, with one angle being exactly 90 degrees.

    Obtuse Scalene Triangle

    • Possesses one angle greater than 90 degrees.
    • All sides are of different lengths.

    Acute Equilateral Triangle

    • All three sides are equal in length.
    • Each angle measures 60 degrees.

    Right Isosceles Triangle

    • Is a right triangle with two legs of equal length.
    • Contains angles of 45°, 45°, and 90°.

    Obtuse Isosceles Triangle

    • Can be either isosceles or scalene.
    • Has one angle greater than 90 degrees, while the other two angles are equal.

    Acute Isosceles Triangle

    • Defined by two sides of equal length.
    • Excludes the requirement of all angles being acute if considering equilateral as a special case.
