![]() ![]() If we know the unknown angle A, we can easily find the other angle of the Isosceles triangle.Įxample: Consider the isosceles triangle ABC, where B = C and A = 70°. If we are given the measure of an uneven angle, we can simply use the angle sum property to determine the other two angles.Īssume we have an isosceles triangle ABC, with AB = AC and B = C. ![]() The Isosceles triangle has the same angle sum property as the triangle. As a result, one of the angles is uneven. Although an equilateral triangle is also an isosceles triangle, the opposite is not necessarily true.Īlso check: Types of Triangles in Maths based on Sides Isosceles Triangle AnglesĪn isosceles triangle has three angles like a triangle, but it is a peculiar instance since two of the three angles of the isosceles triangle are equal in measure, which is opposite to the equal sides. The two equal-length sides of an isosceles triangle are termed the legs, while the third side of the triangle is called the base. As a result, ∠A and ∠B are equal.Īn isosceles triangle has two equal sides and two equal angles. The angles opposite the equal sides are known to be equal. In the diagram below, ABC is an isosceles triangle with equal sides AC and BC. In other words, An isosceles triangle is a triangle with two congruent sides. Furthermore, the angles opposing an isosceles triangle’s equal sides are equal. What is Isosceles Triangle?Īn isosceles triangle is a triangle having two equal sides. As a result, if a triangle has two equal sides and two equal angles, it is an isosceles triangle. If any two of them are equal, we call this an Isosceles triangle. Triangles are three-sided polygons that are classed as equilateral, isosceles, or scalene depending on the length of their sides. Isosceles Triangle DefinitionĪ triangle is a closed two-dimensional figure with three sides, three vertices, and three angles. In this article, we will look at the definition of an isosceles triangle, its properties, and several isosceles triangle formulas. An isosceles triangle has two angles that are equal in size and opposite from equal sides. Isosceles Triangle: In the study of geometry, An isosceles triangle is a triangle with two sides that are the same length.
