A 45-degree angle is an acute angle
A 90 degree angle is a right angle
No.
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.
180 degrees minus 102 degrees equals 78 degrees.
Supplementary means they add to 180 degrees. If one is 102, then the other is 180 - 102 = 78 degrees.
Remember the two equations. Exterior angle = 360 / no. of sides. Interior angle = 180 - exterior angle. So for 102 sided polygon. exterior angle = 360/102 = 3.5294... Interior angle = 180 - 3.5294... = 176.4706.... Hence sum of the 102 sided polygon's angles is 102 X 176.4706 = 18,000 degrees. ( to nearest degree).
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. In this case, the supplement of a 148-degree angle would be 180 degrees minus 148 degrees, which equals 32 degrees. So, the supplement of a 148-degree angle is a 32-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.
