Because the whole triangle equals 180 and a straight line equals 180. it doesn't matter what kind ( right,isosceles,scalene, or equalateral) it really doesnt matter.
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
Because the 3 interior angles of a triangle must add up to 180 degrees and not 1 angle on its own
If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute
You can't. All the angles in a triangle will add up to 180 degrees, therefore a triangle with one angle greater than this is impossible.
No, it can't be. 'Acute' means that all the angles are under ninety degrees; therefore, a ninety degree angle would make it impossible to have an acute triangle.
no, it is impossible an angle of an equilateral triangle is always 60 degrees it can't be 90 degree
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
Because the 3 interior angles of a triangle must add up to 180 degrees and not 1 angle on its own
It is impossible to have a 180 degree angle because all three of a triangle's angles have to equal 180. If you have one angle of 180, then you would have 2 angles of 0, making a plain old straight line.
A right angle triangle
If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute
You can't. All the angles in a triangle will add up to 180 degrees, therefore a triangle with one angle greater than this is impossible.
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
The third angle is 68 degrees which makes it a scalene triangle
A right angle triangle
A 90o angle is a right angle, and a triangle with a right angle is called a right triangle.
No, it can't be. 'Acute' means that all the angles are under ninety degrees; therefore, a ninety degree angle would make it impossible to have an acute triangle.
