Question

3 a scalene triangle has ____
no sides equal in length
two equal angles
all three sides the same length
two sides equal in length

Explanation:

A scalene triangle is defined as a triangle where all three sides have different lengths (i.e., no sides are equal in length). A triangle with two equal sides is isosceles, and one with all three equal sides is equilateral. Two equal angles would correspond to an isosceles triangle (by the isosceles triangle theorem, equal angles imply equal sides). So the correct description for a scalene triangle is having no sides equal in length.

Answer:

A. no sides equal in length
