The opposite angles of a quadrilateral inscribed in a circle are?
The opposite angles of a quadrilateral inscribed in a circle are supplementary, meaning they add up to 180 degrees. This is due to the property that the sum of the opposite angles of any quadrilateral inscribed in a circle is always 180 degrees. This property can be proven using properties of angles subtended by the same arc in a circle.
Why do all the internal angles of a square equal 360 degrees?
It can be proven that the sum of all the internal angles of a polygon with n sides is (n-2)*180 degrees. In the case of a square, n = 4 and so the angles sum to (4-2)*180 = 2*180 = 360 degrees.
Is the sum of the measures of the angles is 180 degrees?
In a triangle, the sum of the measures of the angles is 180 degrees.
What are supplementary angles?
supplementary angles are angles that have a sum of 180*.another way to remember that its 180* is the two p's in the word make 8.example. 70*+110*= 180* supplementary.Complementary angles add up to 90 degrees.Supplementary angles are two angles whose sum add up to 180 degrees. Can be shown as (180 - x)
2 angles whose sum is 180?
2 angles whose sum is 180 are called supplementery angles.an example of supplementary angles are two right angles.=)
