What kinds of angles does a triangle have?
A triangle can have different combinations of angles depending on its type:
Acute Triangle: All three angles are less than 90° (all acute angles).
Right Triangle: One angle is exactly 90° (one right angle and two acute angles).
Obtuse Triangle: One angle is more than 90° (one obtuse angle and two acute angles).
Explanation
The chapter explores triangles made with straws and discusses the types of angles they can have based on their shape.
