Is a straight line 180 or 90?
180 degrees form a straight line, while 90 degrees form a perpendicular line.
Is a straight line 360 degrees?
Angles are measured in degrees, written °. The maximum angle is 360°. This is the angle all the way round a point. Half of this is the angle on a straight line, which is 180°.
Is a straight line 90 degrees?
We've already said that a straight line contains 180 degrees. This means that if two or more angles lie in a straight line, the sum of their angles is 180 degrees.

How many degrees is in a triangle?
180°Triangle / Sum of interior angles
What is the degree of a triangle?
180 degrees The sum of the three angles of any triangle is equal to 180 degrees.
What degree is a triangle?
The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
