Final answer:
A triangle with two equal sides is termed an Isosceles triangle. This classification is distinct from Equilateral and Scalene triangles that are categorized by side lengths.
Step-by-step explanation:
B) Isosceles The type of triangle with two equal sides is called an Isosceles triangle. In geometry, when categorizing triangles based on their side lengths, there are three primary types: Equilateral, with all three sides equal; Scalene, with no sides equal; and Isosceles, with two sides that are equal in length. The classification of triangles based on angles includes Acute (all angles less than 90 degrees), Right (one angle exactly 90 degrees), and Obtuse (one angle greater than 90 degrees).
However, the question specifically asks about a triangle with two equal sides, which directly corresponds to the Isosceles category.An equilateral triangle has three equal sides, so all angles are 60 degrees. A scalene triangle has no equal sides, meaning all three angles can be different. A triangle with two equal sides is called an isosceles triangle.The answer is Isosceles.
