Equilateral: equal sides and angles(60 degrees)
Isosceles: two equal sides and angles
Scalene: no equal sides or angles
right triangle: has a 90 degree angle in it
obtuse triangle: has an obtuse angle in it
acute triangle: is made up of all acute angles
Triangles.
All triangles have three sides
A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.

No. Triangles all have three sides.
Triangles.
Triangles can be classified into different shapes. Equilateral ; All sides the same length ; all angles equal 60 degrees. Isosceles ; Two sides the same length ; two angles equal size. Right-Angled ; Three sides can be of different lengths ; MUST have one right-angle. Scalene ; All sides of different lengths ; all angles of different size. Common 2-dimensioanal characteristics for ALL triangles. ; - They contain three(3) sides They contain three(angles) The internal angles ALWAYS sum to 180 degrees. A triangle may also be named a TRIGON ; A polygon of three sides. NB Triangles drawn on a 3-dimensional surface ( sphere ), the above characteristics can vary.

The set of all triangles, probably.
All triangles have three sides. Hence "tri" meaning three and "angle" meaning... angle. Three angles. Three sides. All triangles have these.
Scalene triangles. All three are different: Scalene Two are the same: Isosceles All three are the same: Equilateral
No- triangles with all angles respectively equal need not be congruent. For example, all equilateral triangles have 3 angles of 60 degrees each but the the sides could be any length. However the sides of such triangles are proportional - such triangles are called similar. They look alike except for their scale.
