Vertices are the main property of triangles. No vertices, no triangle.
All triangles have exactly three vertices.
A right angled triangle.
3 vertices in a triangle, whether it is equilateral, isosceles or scalene; acute angled, right or obtuse.
A right-angled triangle must have acute angles at the other two vertices because those two angles have to be less than 90 degrees.
An acute angled triangle, right angled triangle or obtuse angled triangle.
a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
acute angled triangle,right angled triangle,obtuse angled triangle,isosceles triangle,equilateral triangle, scalene triangle
a right angled triangle is special because it is the only triangle that has a right angle with a dregree of 180.
The right-angled triangle.
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.
Yes.
An obtuse angled triangle is wider than a right angled triangle. It has 180 degree angles.
