What type of triangle has two equal sides?

• A. Equilateral
• B. Right
• C. Scalene
• D. Isosceles

Answer: (D)

A triangle that has two equal sides is known as an isosceles triangle. This type of triangle is characterized by having at least two sides that are the same length, which also results in the angles opposite those sides being equal. In more detail, an isosceles triangle can be identified by its symmetric properties, allowing it to maintain balance in shape and provide uniformity in its angles. When you visualize or draw an isosceles triangle, you will notice that the two equal-length sides converge at a vertex angle, making the triangle distinct from others. Other types of triangles have different characteristics. For instance, an equilateral triangle features all three sides of equal length and all angles equal, making it a unique case of isosceles as well. A right triangle, on the other hand, is defined by having one angle that measures 90 degrees, and it may or may not have equal sides, thus not fitting the criteria of having exactly two equal sides. A scalene triangle has all sides of different lengths and no equal angles, which again does not meet the requirement of having two equal sides. Therefore, the defining trait of having two equal sides firmly identifies the triangle as isosceles. This understanding is fundamental
