Answer:
A. Equilateral,
D. Acute,
F. Isosceles.
Step-by-step explanation:
We have been given an image of a triangle and we are asked to classify our given triangle.
We can see from our given triangle that its all angles are equal, therefore, our triangle is an equilateral triangle and option A is a correct choice.
Since all the angles of an equilateral triangles equal to 60 degrees and our triangle has no angle that measures 90 degrees or more than 90 degrees, therefore, our triangle is neither right nor obtuse triangle and option B and C are not correct.
Since all the angles of an equilateral triangles equal to 60 degrees, therefore, our triangle is also acute triangle and option D is the correct choice.
Since all sides of a scalene triangle are unequal, while all sides of an equilateral are equal, therefore, our triangle is not a scalene triangle and option E is not correct.
An isosceles triangle has two equal sides, while an equilateral has three equal sides, therefore, every equilateral triangle is isosceles and option F is correct.
