Question

Choose the shape with an obtuse angle.

Answer 1

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. Shapes that may contain an obtuse angle include:

- An obtuse triangle (one of the angles is obtuse)
- A scalene triangle (it can have an obtuse angle)
- A trapezoid (if one of the angles is greater than 90 degrees)

If you have specific shapes in front of you, you can look for one that contains an angle greater than 90 degrees. If you describe the shapes, I can help identify which one has an obtuse angle!
