Question

The links of two sides of a triangle are 15 inches each. The third side measures 10 inches. What type of triangle is this? Explain your answer using geometric terms.

Answer 1

It is an isosceles triangle

Explanation:

An isosceles triangle is a type of triangle in which the length of two of the sides are equal and the length of the third side is different. For an isosceles triangle, the base angles of the triangle is equal.

Recall, as we have 3 sides in a triangle, we also have 3 interior angles. Now, for an isosceles triangle, out of these three angles , two of the angles have equal values and as such qualifies the triangle to be called an isosceles triangle.

It should be noted that this should not be mixed up with equilateral triangle where all the sides are equal in length. Only two of the sides here actually are equal in length for an isosceles triangle
