Angles between 90 and 180 degrees are called obtuse.
Congruent angles
Obtuse
90 and 90 170 and 10 60 and 120 The list could go on forever.
Supplementary angles are 2 angles whose measures = 180o.
If one angle is 10 degrees, its opposite angle is also 10 degrees. Since consecutive angles are supplementary, each pair of angles has to add up to 180 degrees so the other angles have to be 170 degrees. Therefore this parallelogram has two 10 degree angles and two 170 degree angles.
They are called obtuse angles.
The gun that measures angles are called "clinometers". We used them in Geography and maths as well! :)
supplementaryA:Two angles whose sum measures a right angle are complementary angles.
They are then complementary angles
Supplementary angles!
A pair of supplementary angles.
