These triangles are impossible:
-- a triangle with more or fewer than three sides
-- a triangle with more or fewer than three angles
-- a triangle with three interior angles that add up to less than 180 degrees
-- a triangle with three interior angles that add up to more than 180 degrees
-- a triangle with a side that's longer than the sum of the lengths of the other two sides
-- a triangle with one 90-degree angle in it, where the square of the length of the longest side
is not the same as the sum of the squares of the lengths of the other two sides
right obtuse triangle
This is impossible, as a hypotenuse is only found on a right triangle.
A quadrilateral triangle is an impossible shape. A quadrilateral has four straight sides while a triangle has three.
The largest angle in a triangle is opposite to its longest side
The shape of the triangle - and its size - will determine its area. There is no information about the triangle provided and so there cannot be a sensible answer.
Two sides of a triangle are not enough to determine its shape and so it is impossible to find its area.
Below is the link to a sweet video on how to make the impossible triangle.
you can't, it's impossible
If a triangle has a right angle, it is a right triangle.
right obtuse triangle
there will be a right angle in the triangle.
This is impossible, as a hypotenuse is only found on a right triangle.
It is impossible for a right angled triangle to be equilateral unless it has a double triangle.
The three vertices of the triangle uniquely determine a circle that circumscribes the triangle. The three sides of the triangle uniquely determine the circle that inscribes the triangle.
a right obtuse triangle, a scalene triangle, and a right equilateral triangle
you cant
it is impossible* * * * * Although it is impossible to have a triangle with no sides or angles congruent to anything else in the 2-d world, I suggest that the answer to this question is a scalene triangle.
