Question

1. true or false: all isosceles triangles are also equilateral triangles. false true 16. if a side in an equiangular triangle measures 2\, then the other two sides sum is... 2\ 4\ 6\ cannot be determined

Explanation:

Question 15

An isosceles triangle has at least two equal sides, while an equilateral triangle has all three sides equal. So, not all isosceles triangles are equilateral (e.g., a triangle with sides 2, 2, 3 is isosceles but not equilateral).

Step1: Recall equiangular triangle properties

An equiangular triangle is also equilateral, meaning all sides are equal. So if one side is \( 2'' \), all sides are \( 2'' \).

Step2: Calculate sum of other two sides

The other two sides are each \( 2'' \), so their sum is \( 2'' + 2'' = 4'' \).

Answer:

A. False
