Angles aren't congruent. Equal angles do not add up to 90 degrees unless they are 45 degrees. Complementary angles, by definition, add up to 90 degrees.
It is: 90 degrees because supplementary angles add up to 180 degrees.
Nope. It is complementary angles that add to 90 degrees.
-- one of them is 90 degrees -- the other two add up to 90 degrees
A Right Isosceles Triangle is a shape that has one 90° angle. 90 degrees + the other two angles add up to 180 degrees.
No. Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees.
Complementary Angles add up to 90 degrees. Supplementary Angles add up to 180 degrees.
Angles aren't congruent. Equal angles do not add up to 90 degrees unless they are 45 degrees. Complementary angles, by definition, add up to 90 degrees.
90 degrees, supplementary angles add up to 180*90 degrees.
Yes, a triangle has a total of 180 degrees of its angles. Since a right triangle has one angle that is 90 degrees, the other two angles much add up to 180-90=90 degrees. 65+25=90.
It is: 90 degrees because supplementary angles add up to 180 degrees.
Two angles that add up to 90 degrees are called complementary angles.
Complementary angles add up to 90 degrees
you turn the padlock so the numbers are facing you and you pull up the metal bit and turn it 90 degrees to your left. Then you push down
An angle that adds up to 90 degrees is a complementary angle. It consists of two acute angles.
90 degrees
The answer would be 90 degrees, because the quadrilateral's angles should add up to 360 degrees. 360 - (60 + 120 + 90)= 90 120 + 60 = 180 + 90 = 270 + 90 = 360
