Question

1. classify the triangle by its angles and sides. acute scalene equiangular equilateral acute isosceles obtuse isosceles

Explanation:

Step1: Analyze the sides

The triangle has two sides marked as equal (by the tick marks), so it is an isosceles triangle (a triangle with at least two equal sides).

Step2: Analyze the angles

All the angles in the triangle are acute (less than \(90^{\circ}\)). Visually, there is no right - angle (\(90^{\circ}\)) or obtuse angle (greater than \(90^{\circ}\) but less than \(180^{\circ}\)).

Answer:

acute isosceles
