Question

True or false? In an isosceles triangle all sides are unequal.

Answer 1

An isosceles triangle is a triangle with (no less than) two equivalent sides. In the figure beneath, the two equivalent sides have length and the staying side has length . This property is proportionate to two edges of the triangle being equivalent. An isosceles triangle in this way has both two equivalent sides and two equivalent points. The name gets from the Greek iso (same) and skelos (leg). 

A triangle with all sides square with is called an equilateral triangle, and a triangle without any sides approach is known as a scalene triangle. An equilateral triangle is in this way an uncommon instance of an isosceles triangle having not only two, but rather each of the three sides and edges parallel. Another uncommon instance of an isosceles triangle is the isosceles right triangle.

Answer 2

False, an isosceles triangle has 2 equal sides.
