0. A right triangle, by definition, will never include any obtuse angles.
No, that's not true.
ALL quadrilaterals have four sides and four angles. That's what 'quadrilateral' means. The quadrilaterals include the parallelogram, the trapezium, the kite, and the irregular quadrilateral. The parallelograms include the rhombus and the rectangle. The rhombus and the rectangle both include the square.
Classroom items that have acute angles include pencils, scissors, rulers, and notebooks. Acute angles are angles that measure less than 90 degrees, so any object with sharp corners or edges likely has acute angles. These items can be used to teach students about geometric concepts such as angles and shapes in a hands-on way.
