Classify the following triangle. check all that apply.

Options A and D are the correct choice.

Step-by-step explanation:

We are asked to select all the correct option from the given choices.

A. We can see that one angle is marked as 90 degrees. We can also check it by Pythagorean theorem as,

Rounding our answer we will get,

From above equation we can conclude that our triangle is a right triangle.

B. This is not an isosceles triangle as all of its sides are of different length.

C. This can't be an acute triangle as it has one 90 degree angle. In order to be an acute triangle all angles should be less than 90 degrees.

D. We can see that all three sides of our triangle are unequal, therefore, it is a scalene triangle.

E. None of angles of our triangle are greater than 90 degree, therefore, it is not an obtuse triangle.

F. All sides of an equilateral triangle must be of equal length and its all interior angles are congruent.Therefore, our triangle is not equilateral triangle.

Therefore, options A and D are correct.
