a line or supplementary angles.
No. Only the sum of the measures of the angles of a triangle equal to 180 degrees; in the case of a quadrilateral it amounts to 360 degrees.
180 degrees
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
the sum ofall 3 angles of a triangle is 180 degrees. If all of them are equal, then each is 60 degrees.
Supplementary Angles
Supplementary angles are two angles that, when added together, are equal to 180 degrees.
180 degrees
All the angles together equal 180, so take the two known angles and subtract them from 180.
3. They must added together equal 180 degrees.
Supplementary angles are angles that add together to equal 180, which is different from complementary angles that equal 90. So 180-37=143.
A supplementary angle is 180 degrees. So, it depends how many supplementary angles you add together.
The angles that are equal to 180 are called supplementary angles. The angles that equal 90 degrees are called complimentary.
angles that equal to 180
One right angle is equal to 90 degrees, or a vertical line extending from the o degree plane. Therefore, two right angles, presumably side to side, would have 180 degrees, since together the would be supplementary angles. Supplementary angles are two angles which combine to from 180 degrees, and 90 plus 90 would equal 180 degrees. Look at angle DBE and at angle EBC. Each are 90 degree angles, or right angles, and together equal 180 degrees.
easy! triangle
Their measurements must equal 90° when added together. Supplementary is 180°.
