Question

classify the triangle by its sides and by measuring its angles.
this triangle can be classified by its angles as
and by its sides as
equilateral
acute
right
obtuse
equiangular
isosceles
scalene

Explanation:

Step1: Recall triangle classification by angles

Triangles are classified by angles as acute (all angles < 90°), right (one angle = 90°), obtuse (one angle > 90°), or equiangular (all angles equal). Since no angle - specific measurement is given, but for an equilateral triangle (by sides), all angles are 60°, so it is equiangular.

Step2: Recall triangle classification by sides

Triangles are classified by sides as scalene (no equal sides), isosceles (two equal sides), or equilateral (all sides equal). The triangle in the image has all sides marked as equal.

Answer:

Equiangular; Equilateral
