180 degrees in an equilateral triangle.
90 degress :P
Lines are not measured in degress, however there is a straight angle which measures 180 degrees.
30 degrees
anything over 180, A triangle is composed of 180 degrees, so if one angle alone is 180 degress then the shape is not A triangle.
The 3 interior angles of any triangle add up to 180 degrees.
There are 180 degrees in a triangle.
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
180 degrees
180 degrees in an equilateral triangle.
Vertex angle: 180-42-42 = 96 degrees
An angle of 200 degrees is a reflex angle
90 degress :P
Lines are not measured in degress, however there is a straight angle which measures 180 degrees.
180 - (80 + 60) ie 40
30 degrees
anything over 180, A triangle is composed of 180 degrees, so if one angle alone is 180 degress then the shape is not A triangle.
