What are the classifications of a triangle?

The classifications of a triangle are:Right Triangle- has one angle that is 90 degreesEquilateral Triangle- has three equal sides and three equal angles (each is 60 degrees)Isosceles Triangle- has two equal sides and two equal anglesScalene Triangle- has no congruent sidesAcute Triangle- has three acute angles (less than 90 degrees)Obtuse Triangle- has one obtuse angle (more than 90 degrees)


What are the names of the 6 different triangles?

Classifications by side length or comparison of angles and sides:scalene - no sides or angles equalisosceles - two sides and angles equal (congruent)equilateral - all sides and angles equal (all 60&deg; angles)Classifications by included angles :right triangle - contains a 90&deg; angle (right angle)oblique triangle - has no right angleacute triangle - contains all angles less than 90&deg;obtuse triangle - contains one angle greater than 90&deg;


How do you spell the names of different triangles?

Classifications by side length or comparison of angles and sides:scalene - no sides or angles equalisosceles - two sides and angles equal (congruent)equilateral - all sides and angles equal (all 60&deg; angles)Classifications by included angles :right triangle - contains a 90&deg; angle (right angle)oblique triangle - has no right angleacute triangle - contains all angles less than 90&deg;obtuse triangle - contains one angle greater than 90&deg;


What are the 4 different names of triangles?

Classifications by side length or comparison of angles and sides:scalene - no sides or angles equalisosceles - two sides and angles equal (congruent)equilateral - all sides and angles equal (all 60&Acirc;&deg; angles)Classifications by included angles :right triangle - contains a 90&Acirc;&deg; angle (right angle)oblique triangle - has no right angleacute triangle - contains all angles less than 90&Acirc;&deg;obtuse triangle - contains one angle greater than 90&Acirc;&deg;*Note that a triangle can be more than one type. A right triangle is a special case of either a scalene or isosceles triangle.
