What do you call two angles that equal 180 degrees?
a line or supplementary angles.
Is the sum of the measures of the angles of a quadrilateral equal to 180 degrees?
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.
What should the sum of the angles of a triangle equal?
180 degrees
What are two angles called whose sum is 180 degrees?
Angles that add up to 180 degrees are called supplementary angles.
Is the perimeter of a triangle equal 180?
The sum(addition) of the measures of the three angles of a triangle is 180 degrees.
What is the name of 2 angles that equal 180 degrees?
Supplementary Angles
How much are supplementry angles?
Supplementary angles are two angles that, when added together, are equal to 180 degrees.
What do all of the angles in a triangle equal when added together?
180 degrees
How do you find an angle of a triangle if you have the two other angles?
All the angles together equal 180, so take the two known angles and subtract them from 180.
How angles does a triangle has?
3. They must added together equal 180 degrees.
Angle x has a supplementary angle measuring 37degrees what is the measure of x?
Supplementary angles are angles that add together to equal 180, which is different from complementary angles that equal 90. So 180-37=143.
What are 2 angles called if the sum of their measures is equal to 180?
The angles that are equal to 180 are called supplementary angles. The angles that equal 90 degrees are called complimentary.
What do Supplementary angles equal?
A supplementary angle is 180 degrees. So, it depends how many supplementary angles you add together.
What is a supplermentary angles?
angles that equal to 180
How much degrees are two right angles?
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.
What is the name of a polygon whose interior angles equal 180?
easy! triangle
What has to be true for two angles to be complementary?
Their measurements must equal 90° when added together. Supplementary is 180°.
