Study Notes

Types of Triangles

Acute Triangle: All three angles are acute (less than 90 degrees).
Right Triangle: Contains one right angle (exactly 90 degrees).
Obtuse Triangle: Features one obtuse angle (greater than 90 degrees).
Equiangular Triangle: All angles are congruent, therefore each angle measures 60 degrees.
Scalene Triangle: No sides are of equal length; all sides are different.
Isosceles Triangle: Contains at least two sides of equal length, which results in two equal angles.
Equilateral Triangle: Special case of isosceles; all three sides are congruent, leading to three equal angles of 60 degrees each.
