Question

classify the triangle by its sides and by measuring its angles. the triangle can be classified by its angles as and by its sides as.

Explanation:

Step1: Classify by angles

A right - angled triangle has one angle equal to \(90^{\circ}\). In \(\triangle MNL\), \(\angle N = 90^{\circ}\), so by angles, it is a right - angled triangle.

Step2: Classify by sides

A scalene triangle has all sides of different lengths. Since there is no indication of equal side lengths in the given triangle \(\triangle MNL\), by sides, it is a scalene triangle.

Answer:

By its angles: right - angled triangle; By its sides: scalene triangle.
