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

What are three different types of triangles?
equilateral,isosceles and scalene
What three shapes can be put together to make a trapezoid?
Three triangles.
If two triangles have three pairs of congruent angles then the triangles are not guaranteed to be congruent?
Correct. Congruency means that two triangles have three pairs of congruent angles and corresponding sides of the same lengths. A pair of triangles with three pairs of congruent angles but sides of different lengths are similar, not congruent.
How many distinct triangles can be constructed by connecting three different vertice's of a cube?
one
What are the names of the triangles by side lenghts?
Scalene triangle = All sides are different lengths Isosceles triangle = Two sides have the same length Equilateral triangle = All three sides are the same length
What are the names of the three triangles?
Equilateral, Isosceles and Scalene.
Are triangles similar?
there are three different triangles. the iscocelese, equalateral and right. so no
What triangles always have three sides of different lengths?
Scalene triangles. All three are different: Scalene Two are the same: Isosceles All three are the same: Equilateral
What are isosceles triangels?
Isosceles triangles are triangles in which two of the three sides have different lengths.
What is an example of a sentence with a triangle in it?
There are three different types of triangles; equilateral, isosceles, and obtuse triangles.
What shape has three different sized 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.
What are the names of all triangles and their definitions?
What is the names of all the triangles?
Different types of triangles?
Three, Isoceles, Scalene & Equilateral.
What are three different types of triangles?

Do scalene triangles have three different length sides?
Yes.
What three shapes can be put together to make a trapezoid?
Three triangles.
What are the properties of the different types of triangle?
There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.
