To classify triangles by the measure of their sides you must use the names:

• Equilateral, Equiangular and Obtuse

• Equilateral, Isosceles and Scalene

• Right triangle, Scalene and Equiangular

• Isosceles, Scalene and Equiangular

To classify triangles by tne measure of their angles we use the names:

• Equiangular, Isosceles and Acute

• Acute, Obtuse and Isosceles

• Right triangle, Isosceles triangle and Scalene triangle

• Right triangle, Obtuse triangle and Acute triangle

When the triangle has one right angle it is called:

• Acute triangle

• Obtuse triangle

• Right triangle

• Scalene triangle

When a triangle has an obtuse angle inside it is called:

• Right triangle

• Obtuse triangle

• Acute triangle

• Isosceles triangle

If a triangle has three acute triangles inside it is called:

• Acute triangle

• Obtuse triangle

• Right triangle

• Isosceles

• 360

• 90

• 150

• 180
