Question

Which set of measurements

represents the lengths of an
isosceles triangle?
A) 3cm, 4cm, 5cm
B) 13in, 13in, 26 in
C) 27in, 27in, 44in
D) 18cm, 18cm, 38cm

Answer 1

c. an isosceles triangle has 2 equal sides.
the reason b and d aren’t true is because the sides add up to be less or equal to the longest side and to make a triangle the 2 sides have to add up to be more than the longest side.
