If each triangle below is drawn accurately, identify whether it is most likely an obtuse, acute, or right triangle. Label the angle or angles that helped you to decide. Homework Help ✎
Examine all three angles of this figure.
Are any of the angles greater than, less than, or equal to 90°?
The box on angle A indicates that angle A is a right angle.
The figure is therefore identified as a right triangle.
This figure is an obtuse triangle because one of its angles is greater than 90°.
Can you explain why this is an acute triangle?
