Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
a plane triangle is a normal triangle, like the isosceles, right angled, equilateral and scalene triangle.
It will look like one half of a 12 x 12 square cut through diagonally. The hypotenuse angle will be 45 degrees.
If a triangle has a right angle, it is a right triangle.
It is a triangle where all no side is equal in length or angle.
it can be a triangle that is right, acute, or obtuse
any right triangle with thickness
it is a right angle triangle
It looks like the diagram below./\
An isosceles triangle has two same sides and one different side.
Like a right angle with a line joining the 2 ends.
A right angle triangle or an obtuse triangle
The angles would need to be equal to 60 degrees, so it would be an acute triangle. The triangle would look like a normal equilateral triangle.
no right angle with only one angle is obtuse
A triangle is composed of 180 degrees. Two right angles = 180 degrees, the total number for all angles in a triangle. Thus a triangle can not have more than one right angle. l____________l <------ This is what two right angles look like, as you can see it cannot ever be a triangle.
It will look like a right angle triangle with a 90 degree angle and two 45 degree angles and will have one line of symmetry
A right angled triangle.
