In an isosceles triangle, two angles are equal in measure.

Do Isosceles Triangles have Equal Angles? In a triangle, if any two sides are of equal length, it is considered to be an isosceles triangle. How do you know if a Triangle is Isosceles?Ī triangle can be scalene, isosceles, or equilateral when classified on the basis of the length of its sides. The converse of the isosceles triangle theorem is also true which states that in a triangle if two angles are equal then the sides opposite to those angles are also equal. The isosceles triangle theorem states that when two sides are equal, the base angles are also equal. Following this fact, if two sides of a triangle are equal, then the angles opposite to those sides are also equal.

The perpendicular bisector drawn from the apex angle bisects that angle and the unequal side of the triangle. CriteriaĪll three sides are of different measurements.Īll three angles are equal and measure 60° each. Observe the table given below to understand the differences and similarities in scalene, equilateral, and isosceles triangles. A scalene triangle is one in which all three sides and all three angles are of different measurements, an equilateral triangle is one with all three sides and angles equal, and in an isosceles triangle, two sides and two angles are equal in measurement. Each triangle is different from the other on the basis of its unique properties.
