1 All triangles are 2 dimensional 3 sided polygons
2 All triangles have 3 interior angles that add up to 180 degrees
3 All triangles have 3 exterior angles that add up to 360 degrees
4 All triangles have a perimeter which is the sum of their sides
5 All triangles have an area which is 0.5*base*perpendicuar height
6 All triangles will tessellate
7 All other polygons are made up of triangles
8 All triangles have no diagonals
9 All triangles are classified as follows:-
10 Right angle: which has a right angle and 2 acute angles
11 Obtuse: which has an obtuse angle and 2 different acute angles
12 Scalene: which has 3 different acute angles
13 Isosceles: which has 2 equal base angles and an apex angle
14 Equilateral: which has 3 equal 60 degree angles
15 An equilateral has 3 lines of symmetry
16 An isosceles has only 1 line of symmetry
17 The rest have no lines of symmetry unless it is a 90 45 45 triangle
18 Trigonometry which means 3 measurements is based on triangles
19 Pythagoras' theorem takes care of right angle triangles
20 Triangles can be constructed into pyramids
What else can I help you with?
What different triangles can you draw at least one angle of 60 degrees?

How many triangles and trapezoids make a hexagon?
You need at least four triangles, or at least three trapeziums. Or two triangles and one trapezium.

Do all triangles have at least 1 right angle?
only right tringles or HL triangles have at least 1 right angle
How many triangles have at least two equal sides?
equilateral triangles and isosceles ones
Are angles in an isoceles triangle equal?
Isosceles triangles have at least 2 equal angles. The 3rd angle can either be equal to the other two (it's then called an equilateral triangle), or it can be different from the two equal angles, in which case it's an isosceles triangle. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.
What is the least amount of triangles you could fit into a nonagon?
The smallest number of triangles that you could divide a nonagon into is seven.
Do all triangles have at least to acute angles?
Yes.
How many triangles are there in a quadrilateral?
You can divide a quadrilateral up into as many triangles as you want, but at least two.
Are all equilateral triangles also isosceles triangles?
Yes, an isosceles triangle is a triangle that has at least two congruent sides.
