Questions: A) acute isosceles B) obtuse isosceles C) equilateral D) acute scalene E) obtuse scalene

Solution Steps

The markings on the triangle's sides indicate that two sides have equal lengths. The angles all appear less than 90 degrees.

Since two sides are equal, it is an isosceles triangle. Since all angles are less than 90 degrees, it is an acute triangle. Therefore, the triangle is an acute isosceles triangle.

Final Answer: The final answer is $\boxed{A}$
