Question

what kind of triangle is this?
acute
right
obtuse

Explanation:

Step1: Recall triangle type definitions

An acute triangle has all angles less than \(90^\circ\), a right triangle has one \(90^\circ\) angle, and an obtuse triangle has one angle greater than \(90^\circ\).

Step2: Analyze given angles

The angles are \(61^\circ\), \(66^\circ\), and \(53^\circ\). All are less than \(90^\circ\).

Answer:

acute (since all angles \(61^\circ\), \(66^\circ\), \(53^\circ\) are less than \(90^\circ\), so it's an acute triangle)
