1. The problem asks to classify a triangle based on its side lengths and angles. 2. The triangle has two equal sides, indicated by the markings, so it is an isosceles triangle. 3. To determine if it is acute or obtuse, we consider the angles. Since no angle is marked as greater than 90 degrees, and typically an isosceles triangle with two equal sides and no obtuse angle markings is acute. 4. Therefore, the triangle is classified as an isosceles acute triangle.
