A right angle triangle.
A right triangle, that is, one with one angle of 90 degrees.
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
They sum to 90 degrees so they are complementary.
A right angles triangle, as one of the angles in the triangle is 90 degrees.
It has 180 degrees, but one angle of the triangle has to be 90 degrees
The question "What are the classifications of a triangle" is answered elsewhere. The angles in a triangle can be either an obtuse >90 degrees, an acute <90 degrees, or a rectal = 90 degrees
A triangle with one angle over 90 degrees is an obtuse triangle.
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees.
Any triangle that has an angle measuring 90 degrees is a right triangle.
A right-angle triangle
rotate it 90 degrees
