This means that if you fold an isosceles triangle along this line of symmetry, the two halves will be congruent. Symmetry: Isosceles triangles have a line of symmetry that passes through the vertex angle and bisects the base.The vertex angle is the angle formed by the two legs of the triangle, and it is always larger than the base angles. Unequal Vertex Angle: The vertex angle of an isosceles triangle is always different from the base angles.This means that if two sides of a triangle have the same length, the angles opposite those sides are also equal. Equal Base Angles: In an isosceles triangle, the base angles are always equal.

The two sides that are equal in length are known as the legs of the triangle. The third side, which is not equal in length to the other two sides, is known as the base of the triangle. Definition of an Isosceles TriangleĪn isosceles triangle is defined as a triangle with two sides of equal length. In this article, we will explore the various properties and characteristics of isosceles triangles. Isosceles triangles have some unique properties that distinguish them from other types of triangles, such as equilateral or scalene triangles. So, the answer to all three parts of the question is \textbf.An isosceles triangle is a type of triangle in which two sides of the triangle have the same length, and the third side is different from the other two. So, it is possible to have an equiangular isosceles triangle. However, an equilateral triangle is also an isosceles triangle because it has at least two sides of equal length. This is also known as an equilateral triangle. Step 3:} An equiangular isosceles triangle is a triangle where all angles are equal. So, it is also possible to have an obtuse isosceles triangle. The sides opposite these equal angles are also of equal length. Step 2:} An obtuse isosceles triangle is a triangle where one angle is greater than 90 degrees and the other two angles are of equal measure. So, it is possible to have an acute isosceles triangle. Step 1:} An acute isosceles triangle is a triangle where all the angles are less than 90 degrees and two sides are of equal length. So, the answer to all three parts of the question is yes, it is possible.
So, it is also possible to have an obtuse isosceles triangle.Īn equiangular isosceles triangle is a triangle where all angles are equal. So, it is possible to have an acute isosceles triangle.Īn obtuse isosceles triangle is a triangle where one angle is greater than 90 degrees and the other two angles are of equal measure. An acute isosceles triangle is a triangle where all the angles are less than 90 degrees and two sides are of equal length.
