How to identify a triangle?
Understand the Problem
The question is asking how to recognize and classify a triangle based on its properties, such as the types of angles or sides it has.
Answer
Check sides and angles: Equilateral has 3 equal sides, Isosceles 2, Scalene none. Right triangle has one 90° angle, Obtuse one >90°, Acute all <90°.
To identify a triangle, examine its sides and angles. An equilateral triangle has 3 equal sides, an isosceles triangle has 2 equal sides, and a scalene triangle has no equal sides. For angles, a right triangle has one 90° angle, an obtuse triangle has one angle greater than 90°, and an acute triangle has all angles less than 90°.
