Question

classify the following triangle according to its sides and its angle measures.

a. scalene acute triangle
b. scalene obtuse triangle
c. isosceles right triangle
d. isosceles obtuse triangle

Explanation:

First, check side lengths: 2 cm, 2.5 cm, 3 cm are all different → scalene. Then check angles: 83°, 53°, 44° are all less than 90° → acute. So it's a scalene acute triangle.

Answer:

a. Scalene acute triangle
