The total when you add up the three angles in a triangle is 180 degrees.
If one angle is 100 degrees, then the total of the other two angles is 80 degrees. This means that those two angles must SMALLER than 90 degrees.
So a triangle with an angle of 100 degrees cannot be a right triangle.
What else can I help you with?
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.
Is an obtuse triangle a right triangle?
its a triangle * * * * * No, it an obtuse triangle is not a right angle triangle. An obtuse angled triangle has one angle which is greater than 90 degrees and the other two are acute. In a right angled triangle, the largest angle is 90 degrees while the other two are acute. So one cannot be the other.
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.
How do you find the nearest degree of a triangle?
You cannot. An angle of a triangle can have any value between 0 and 180 degrees.
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.
Does obtuse triangle have a right angle?
No, an obtuse triangle cannot have a right triangle for the reason that an obtuse angle is greater than 90 degrees; therefore, the other two angles must be lower than 90 degrees.
Can an isosceles triangle have 68 and 10 inches with one 90 degrees angle?
No, it cannot.
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.
Does An Acute Triangle Have Three 90 Degree Or Less?
The sum of the angles of a triangle is 180 degrees so it cannot have three 90 degrees. An acute angle is an angle less than 90 degrees. An acute triangle is one in which all the angles are acute.
Can a triangle have all three types of angles?
no The reason is because a triangle cannot have the sum of its angles exceeding 180 degrees. Having a right angle and an obtuse angle already puts the triangle at over 180 degrees because an obtuse angle must be over 90 degrees. Not to mention that this leaves no room for an acute angle.
What type of triangle has an angle measures 60 degrees and an angle that measures 90 degrees?
It is a right angle triangle and the 3rd angle will measure 30 degrees
What triangle has a 40 degrees angle and a 30 degrees angle?
An obtuse scalene triangle.
