TTYPES OF TRIANGLES ACCORDING TO THEIRANGLES 8. Acute triangle All the angles are acute angles (angles > 90). Acute angleAcute angleAcute angle 9. Right triangle It has one angle equal to 90 (=90).Right angle 10. Obtuse triangle It has one obtuse angle (angle > 90)Obtuse angle 11. Identifying Triangles TRIA N GLES.SID ES. A N GLES.
