What shapes have perpendicular lines?
Two-dimensional shapes made with perpendicular lines include (but are not limited to) right-triangles, rectangles, octagons, and dodecagons. Three-dimensional shapes made with perpendicular lines include (but are not limited to) cubes, octahedrons, cuboctahedrons, and icosahedrons.
What triangles will form a kite?
Any two triangles which are a mirror image of each other will form a kite if their long sides are brought together.
What shape is made out of two right triangles?
Two right triangles, when joined together by their hypotenuses (the side opposite the right angle), will form a rectangle.
What is the math behind a tesselation?
This is a pattern made up of identical shapes, they must fit together without any gaps and the shapes must not overlap. Multiple regular shapes are squares, triangles, hexagons and dodecagons
Composite figures of right triangles in trigonometry?
A composite figure is a figure that is made up of several smaller geometric figures like triangles, circles, or rectangles.
What are some contributions Pythagoras made to mathematics?
his theory for right angled triangles
Can all 4 sided shape be made by two right angled triangles?
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
Can a 4 sided shape be made by two right angled triangles?
Yes, if you put them together correctly.

What triangles will form a kite?
Any two triangles which are a mirror image of each other will form a kite if their long sides are brought together.
Is a rectangle made up of congruent shapes?
I think a rectangle is NOT made up of congruent shapes because it only does not have triangles.
What shape are made from 4 triangles?
Depending on their shapes and sizes you can make plane shapes with 3 to 24 sides.
How triangles are important in your daily lives?
this question made me laugh so i shall answer it Well since triangles are the strongest shapes, many things are made of them. do you cross a bridge on the way to work? chances are its made of triangles.
What are a score or more facts relevant to triangles?
They are as follows:- 1 Triangles are 2 dimensional polygon shapes 2 Triangles have 3 sides 3 Triangles may have acute angles greater than 0 but less than 90 degrees 4 Triangles may have right angles which are 90 degrees 5 Triangles may have obtuse angles greater than 90 but less than 180 degrees 6 Triangles have 3 interior angles that add up to 180 degrees 7 Triangles have 3 exterior angles that add up to 360 degrees 8 Triangles can be scalene which have 3 acute angles 9 Triangles can be right angled with a 90 degree angle and 2 acute angles 10 Triangles can be obtuse with 1 obtuse angle and 2 acute angles 11 Triangles can be isosceles with 2 equal angles and another angle 12 Triangles can be equilateral with 3 equal angles of 60 degrees 13 Triangles have no diagonals 14 Triangles will tessellate 15 Triangles have lines of symmetry when they are isosceles or equilateral 16 Triangles have perimeters which is the sum of their 3 sides 17 Triangles have areas which is 0.5*base*altitude 18 Triangles can be used with Pythagoras' theorem if they are right angled 19 Triangles can be used in conjunction with trigonometry 20 Triangles are found in all other polygons 21 Triangles and their properties were known by the ancient Greeks 22 Triangles can be made into musical instruments
What strategies are there to find the surface area of three-dimensional shapes made from rectangles and triangles?
Find the areas of the rectangles and triangles. Add them together.
What combination of shapes that you could use to make a hexagon?
There are an infinite number of options. Even sticking with polygons with sides of the same measure, a hexagon can be made from 6 equilateral triangles, or 4 eq triangles and a 60 degree rhombus, or 2 eq triangles and 2 60-deg rhombi, or 3 60-deg rhombi. Each of the equilateral triangle could be made from smaller shapes. Eg four equilateral mini-triangles to make 1 triangle. Or 2 mini-triangles and 1 mini-rhombus or 2 60-deg mini-rhombi. And then each of those mini triangles could be made up of smaller micro-shapes. And so on ...
What shape is made out of two right triangles?
Two right triangles, when joined together by their hypotenuses (the side opposite the right angle), will form a rectangle.
