Classify the triangle according to sides.

Question

Quizplus · Accepted Answer

In order to classify a triangle according to its sides, we look to see if all three sides are equal (Equilateral), if no sides are equal (Scalene), or if only two sides are equal (Isosceles). Without knowing the exact measurements of the sides, we can see from the image that the sides are not all equal, but it appears that at least two sides are equal. Therefore, the best choice is C) Isosceles. An isosceles triangle has two equal sides, while the third side is different. As we do not have any information about the length of the sides, we cannot say for sure if it is equilateral or scalene.
