Class 5MathematicsShapes and Angles
Types of Triangles
By sides: Equilateral (all 3 sides equal โ all angles 60ยฐ). Isosceles (2 equal sides โ 2 equal angles). Scalene (no equal sides โ no equal angles). By angles: Acute triangle (all angles acute). Right triangle (one angle = 90ยฐ โ the right angle triangle used in Pythagoras theorem later). Obtuse triangle (one angle obtuse). Important: Angles of any triangle always add up to 180ยฐ!
