What is the sum of the measure of the exterior angles of a quadrilateral?
The sum is two straight angles or 360 degrees.
Two of the angles in a parallelogram each measure 75 degree what is the measure of the other two angles?
Always remember that a quadrilateral's (in this case, a parallelogram's) 4 angles must have a sum of 360 degrees. A quadrilateral has a pair of congruent angles. In this case, if a quadrilateral had 2 sides that have 75 degrees, the other 2 must be congruent, and the sum of all 4 angles must be 360.Let x = 1 of the remaining 2 angles (it doesn't matter which one, because they have the same measure)2x + (75+75) = 3602x + 150 = 3602x = 210x = 105The other angles are both 105 degrees.
If two of the angles of a parallelogram each measure 75 degrees what is the measure of the other two angles?
They measure 105 degrees each.
What are supplementary angles that are NOT a linear pair?
Any two angles whose measures add up to 180 degrees. For example, opposite angles of a cyclic quadrilateral (quadrilateral whose vertices are on a circle).
Do the angles in a 4 sided shape always add up to 360 degrees?
364
