40 and 40
These are supplementary angles
In Geometry that are many different types of polygons. The polygon whose angles equal up to 180 degrees is a triangle.
easy! triangle
a straight line or supplementary angles...which equal to 180 degrees.
A 3-sided polygon is called a "triangle".The angles of a triangle don't equal 180 degrees.They total 180 degrees when they're added.
Two angles whose sum is 180 degrees are called supplementary angles. When two angles are supplementary, it means that the sum of their measures equals 180 degrees. This relationship is often used in geometry to solve for unknown angles or to identify complementary angles.
2 angles whose sum is 180 are called supplementery angles.an example of supplementary angles are two right angles.=)
Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.
The 3 interior angles add up to 180 degrees and the base angles are equal in size
The angles that are equal to 180 are called supplementary angles. The angles that equal 90 degrees are called complimentary.
supplementary angles
Any 3-sided polygon whose internal angles equal to 180 degrees.
