Question

classify the following triangle. check all that apply. a. scalene b. isosceles c. acute d. equilateral e. right f. obtuse

Explanation:

Step1: Check side - length equality

The side - lengths are 5.1, 7, and 8.66. Since all side - lengths are different, it is a scalene triangle.

Step2: Check angle measures

One of the angles is 90° (right - angle symbol is shown). So it is a right triangle.
Since it has a 90° angle, it is not an acute (all angles < 90°), equilateral (all angles 60°), or obtuse (one angle > 90°) triangle. Also, it is not isosceles as no two sides are equal.

Answer:

A. Scalene
E. Right
