Types of Triangles
-
Acute Triangle: Characterized by having all three angles measuring less than 90 degrees.
-
Obtuse Triangle: Defined by having one angle that exceeds 90 degrees, making it the largest angle in the triangle.
-
Right Triangle: Contains one angle that measures exactly 90 degrees, with the other two angles being acute.
-
Equiangular Triangle: A special type of acute triangle where all three angles are equal and congruent, each measuring 60 degrees.
-
Equilateral Triangle: Notable for having all three sides of equal length, which also implies that all angles are congruent and measure 60 degrees.
-
Isosceles Triangle: Identified by having at least two sides that are congruent, which also means the angles opposite those sides are equal.
-
Scalene Triangle: Distinct for having all sides of different lengths, with no congruent sides present.
