Equilateral: 3 equal sides and 3 equal angles Isosceles: 2 equal sides and 2 equal angles Right angle: a 90 degree angle and 2 acute angles and sides that vary in length Obtuse: an obtuse angle and 2 acute angles and sides that vary in length Scalene: 3 acute angles and 3 different side lengths
All right angle triangles have a 90 degree angle and two acute angles and the 3 of them together add up to 180 degrees
equiangular triangle
All triangles have 3 sides and 3 interior angles that add up to 180 degrees:- Right angle triangle has a 90 degree angle and 2 acute angles Scalene triangle has 3 different acute angles Obtuse triangle has 1 obtuse angle and 2 different acute angles Isosceles triangle has 2 equal angles and a 3rd angle that all add up to 180 degrees Equilateral triangle has 3 equal 60 degree angles
No, never.
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
An isosceles triangle has 3 sides 2 of which are equal in lengths An equilateral triangle has 3 sides all of which are equal in lengths
All triangles have 3 interior angles that add up to 180 degrees and they are:- Right angle triangle: 90 degree angle and 2 acute angles Obtuse triangle: An obtuse angle and 2 acute angles Scalene triangle: 3 acute angles of different sizes Isosceles triangle: 2 equal angles and another angle Equilateral triangle: 3 equal angles that each measures 60 degrees
Equilateral: 3 equal sides and 3 equal angles Isosceles: 2 equal sides and 2 equal angles Right angle: a 90 degree angle and 2 acute angles and sides that vary in length Obtuse: an obtuse angle and 2 acute angles and sides that vary in length Scalene: 3 acute angles and 3 different side lengths

right angled triangle
a 3 sided shape is a right angle triangle
No, an equilateral triangle always has 3 equal angles (each angle is 60°)
