Pascal's triangle
You can classify a triangle by its sides or by its angles. I.e: A triangle with three equal sides is an equilateral triangle A triangle with three equal angles is an equiangular triangle A triangle with two equal sides is an isosceles triangle
An isosceles triangle has 3 sides 2 of which are equal in length An isosceles triangle has 3 interior angles 2 of which are the same size
circle, triangle, square and rectangle
Some examples are: circle, square, rectangle, right angle triangle, equilateral triangle

Some examples of the vowel triangle/Benedict triangle include the vowels [i] (as in "see"), [a] (as in "cat"), and [u] (as in "blue"). These three vowels represent the extremes in terms of tongue height and backness when articulating vowels.
An isosceles triangle has 3 sides 2 of which are equal in length An isosceles triangle has 3 interior angles 2 of which are the same size

There are many possible solids. A triangle based prism, or a triangle based dipyramid are two examples.
Infinitely many. The smallest side of a triangle can have infinitely many possible lengths.
Some examples are: circle, square, rectangle, right angle triangle, equilateral triangle
A triangle twice as high as a parallelogram with the same base has the same area.
It is a triangle whose angles add up to 180o Two examples are: A right-angle triangle = 90 + 45 + 45 = 180o An equilateral triangle = 60 + 60 + 60 = 180o
A scalene triangle is a triangle that does not have a right angle in it (i.e. not a right angled triangle) and does not have two (or three) sides with the same length (i.e. not an isosceles triangle or an equilateral triangle). An example is a triangle with sides of length 4cm, 5cm and 6cm.
