A 45-degree angle is an acute angle
A 90 degree angle is a right angle
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.
An angle greater than 90 degree is an obtuse angle.
a 60-degree angle
The complement of a 55 degree angle is a 35 degree angle
A 12 degree angle is an acute angle.
A 90 degree angle is a right angle.
118 degree angle
A 22 degree angle is an acute angle
The supplementary angle to a 145 degree angle will be a 35 degree angle because 145 + 35 = 180.
Straight angle, which is 180 degree, obtuse angle, which is 179 degree to 91 degree, right angle, which is 90 degree, and acute angle, which is 89 degree to 1 degree.
The supplement of a 35 degree angle would be 145 degree angle.
The supplement of a 35 degree angle would be 145 degree angle.
45 degree angle
The compliment of a 100 degree angle is a 80 degree angle.
The supplement of an 80 degree angle is an 100 degree angle.
