Explanation:

Step1: Recall triangle - type definitions

A scalene triangle has no congruent sides. An acute triangle is defined by its angle measures (all angles less than 90°). An isosceles triangle has at least two congruent sides. An obtuse triangle has one angle greater than 90°. A right - triangle has one 90° angle.
So the triangle with at least two congruent sides is an isosceles triangle.

C. isosceles
