Question

classify this triangle by its sides. scalene isosceles but not equilateral equilateral

Explanation:

Step1: Recall triangle side classifications

A scalene triangle has all sides of different lengths, an isosceles triangle has at least two equal sides, and an equilateral triangle has all three sides equal.

Step2: Analyze the given triangle

The triangle is a right triangle (has a right angle). In a right triangle, if it's not isosceles (i.e., the legs are of different lengths), then all three sides (legs and hypotenuse) will be of different lengths. The given triangle has one right angle and two acute angles of different measures (from the diagram, the non - right angles look different), which implies the sides opposite these angles (the legs and hypotenuse) are of different lengths. So it is a scalene triangle.

Answer:

scalene
