Study Notes
Triangle Classifications by Sides
- Scalene Triangle: All sides are of different lengths; no sides are congruent.
- Isosceles Triangle: Has two sides of equal length, creating two congruent sides.
- Equilateral Triangle: All three sides are of equal length; therefore, all sides are congruent.
Triangle Classifications by Angles
- Acute Triangle: Contains three acute angles (less than 90 degrees).
- Obtuse Triangle: Contains one obtuse angle (greater than 90 degrees).
- Right Triangle: Features one right angle (exactly 90 degrees).
- Equiangular Triangle: All three angles are congruent; each angle measures 60 degrees.
Combined Classification
- Right-Scalene Triangle: One right angle with all sides of different lengths.
- Acute-Scalene Triangle: Three acute angles with sides of different lengths.
- Obtuse-Scalene Triangle: One obtuse angle with all sides of different lengths.
- Right-Isosceles Triangle: One right angle with two sides of equal length.
- Acute-Isosceles Triangle: Three acute angles with two sides of equal length.
- Obtuse-Isosceles Triangle: One obtuse angle with two sides of equal length.
- Equiangular-Equilateral Triangle: All sides and angles are congruent, making it both equilateral and equiangular.
