A trapazoid
An irregular pentagon can have 5 vertices and two right-angles.
Two consecutive integers whose sum is 19 is 10 & 9; 10+9 = 19.
A two-fold symmetry has a 360 degrees rotation. A three-fold rotational symmetry, on the other hand, has 120 degrees, and on a horizontal axis, a symmetry has 180 degrees.
A full pie graph is 360 degrees.2/3 of that = 240 degrees.(what is left over is the other one-third = 120 degrees)
Two angles whose sum is 90 degrees are called complementary angles.
They are supplementary angles
They are a complementary pair of angles.
Complementary
They are a supplementary pair of angles.
180 degrees
No. An obtuse angle is an angle whose measure is greater than 90 degrees. If there are two angles whose measures are greater than 90 degrees, then there is no possible way that the sum of the two could be equal to 90 degrees and thus be characterized as complimentary angles.
Two angles whose sum is 90 degrees are called complementary angles. Two angles whose sum is 180 degrees are called supplementary angles. A single angle of 90 degrees is called a right angle.
Two angles the sum of whose measures is 90 degrees are complimentary angles.
They measure 105 degrees each.
two angles whose sum is 90 degrees is a complementary angle.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
