The triangle shown in the image has two equal sides, indicated by the marks on the sides, meaning it is isosceles. Additionally, the angle at the top of the triangle appears to be larger than 90°, making it an obtuse angle.

Thus, the triangle can be classified as an isosceles obtuse triangle.

5. Can a right triangle ever be isosceles or scalene?

Tip: When classifying triangles, focus on both the side lengths (equal or unequal) and the angle types (acute, right, or obtuse).
