What is a triangle containing a 90 degrees angle?
A triangle with a 90° angle is called a "right triangle."
What are 3 kinds of triangle according to angle?
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.
A right angle triangle has one angle of 90?
Yes.The definition of every triangle-Right triangle---A triangle that has one right angle(90 degrees).-Obtuse triangle---A triangle that has one obtuse angle(greater than 90 degrees).-Acute triangle---A triangle that has all acute angles(less than 90 degrees).
What is do you call a triangle with a 90 degrees angle?
A triangle with a 90 degree angle and two acute angles is a right angle triangle.
An acute triangle is a triangle that has what?
an angle less than 90 degrees but more than 0 degrees.So basically, a triangle 89-1 degrees is an acute triangle.
