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
A right angle is defined as 90 degrees, no more or less. If it's not 90 degrees, then it's not a right angle.
Portland is just north of the 45th parallel. So on March 21st and September 21st, the sun is at a 45 degree angle at its highest point of the day. On June 21st, the sun is at a 23 degree angle at its highest point of the day.
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
A slingshot should be oriented at a 45-degree angle for maximum altitude. This angle allows for the greatest amount of potential energy to be converted into kinetic energy directed vertically, resulting in the highest projectile height.
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.
