Step1: Recall triangle - type definitions
An acute - angled triangle has all angles less than 90°. A right - angled triangle has one angle equal to 90°. An obtuse - angled triangle has one angle greater than 90°.
Step2: Analyze Triangle A
Triangle A has a 90° angle. So it is a right - angled triangle.
Step3: Analyze Triangle B
Triangle B has a 120° angle which is greater than 90°. So it is an obtuse - angled triangle.
Step4: Analyze Triangle C
Triangle C has angles 60°, 60°, and 60°, all of which are less than 90°. So it is an acute - angled triangle.
Step5: Analyze Triangle D
Triangle D has a 90° angle. So it is a right - angled triangle.
