Two right angles (90 degrees each) equal 180 degrees (a straight angle).
They are supplementary angles
Only when they are supplementary angles
Supplementary angles are 2 angles whose measures = 180o.
There are three angles in triangles, the measures of which total 180 degrees.
Not possible because all triangles have a total sum of 180 degrees interior angles.
a triangle
In a triangle, the sum of the measures of the angles is 180 degrees.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
Since every type of triangle has a total of 180 degrees of angles, simply deduct the 90 of a right triangle, leaving you with a balance of ___ for the remaining acute angles.
180 degree.
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
A triangle's angles always total 180 degrees
