question 9 of 10
some isosceles triangles are equilateral.
a. true
b. false

Explanation:

An isosceles triangle has at least two equal sides. An equilateral triangle has all three sides equal.

Step2: Analyze the relationship

Since an equilateral triangle has at least two equal sides (in fact, all three), it satisfies the definition of an isosceles triangle. So, some isosceles triangles (the ones that are equilateral) are equilateral.
