The condition of three congruent angles always creates what kind of triangle? a. acute, isosceles, and equilateral b. acute and scalene c. obtuse and equilateral d. right

Step-by-step explanation:

When three angles are congruent, we have each angle of a triangle = 60 degrees.

Whenever two angles are equal we get two sides would be equal. Extending this we get when three angles are equal, three sides are equal.

Since three sides are equal, we call it and equilateral triangle. It cannot be obtuse because all angles are below 90 degrees

when three sides are equal, two sides are automatically equal hence equilateral triangle is also isosceles

Hence we have option a

Acute, isosceles and equilateral.
