Can an obtuse triangle be an right triangle?
No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees
A right triangle is a triangle that has how degrees?
It has 180 degrees, but one angle of the triangle has to be 90 degrees
What type of triangle has an angle that measures 20 degrees and an angle that measures ninety degrees?
It is a right angle triangle and its 3rd angle is 70 degrees.
What is an Right Triangle?
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
Can a right triangle have more than one right angle?
No. It's impossible, obviously a triangle could NOT have more then one right angle. Gosh people are ignorant these days. Remember, the angles of a triangle all have to add up to 180 degrees, and must have THREE angles to be a triangle, and 90, the degrees of a right angle, and 90, the degrees of ANOTHER right angle, equals... 180 degrees. And you simply cannot have a zero degrees angle.
If a triangle has no obtuse angle then it is a right triangle?
It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
A triangle with one angle of 90 degrees?
A right triangle
Can an obtuse triangle be an right triangle?
No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees
What is a triangle called containing a right angle?
It is a right triangle or right-angled triangle. The right-angle is 90 degrees.
Why not left angle triangle but right angle triangle?
Because the phrase 'right angle' indicates 90 degrees whereas there is no such angle as a 'left angle'
What kind of angle do right triangle?
A right triangle has a right angle (thus called a right triangle), 90 degrees
If a triangle has a right angle it is a right triangle. If and only if a triangle had a right angle it is a right triangle?
A right angle triangle has a right angle and two acute angles that all add up to 180 degrees.
Triangle with an angle equal to 90 degrees?
A right angle triangle
A shape with an angle at 90 degrees?
A right angle triangle. (if it is a triangle)
A right triangle has the hypotenuse 12cm and an angle 30 degrees what is the opposite angle?
A right triangle with a hypotenuse of 12cm and an angle 30 degrees has an opposite angle of: 60 degrees.
Does a right triangle have an obtuse angle?
No, a right triangle must have a right angle (by definition). Because there is 180 degrees in a triangle and a right angle is 90 degrees, that leaves the remaining two angles having to equal 90 degrees. Therefore, a triangle cannot have an obtuse angle.
What type of triangle has an angle that measures 20 degrees and and angle that measures 90 degrees?
Any triangle that has an angle measuring 90 degrees is a right triangle.
