The internal angles of any triangle add up to 180 degrees.
A complementary angle is when two angles add up to 90o.
The interior angles of a triangle add to 180 degrees. This is true for any triangle, whether it is obtuse angled, right angles or acute.
A right angle triangle has a 90 degree angle and two acute angles and the 3 angles add up to 180 degrees
No-An equilateral triangle has equal angles, an obtuse angle is greater than 90. So, an equilateral triangle with an obtuse angle would have the three angles add up to a MINIMUM of 270.0000000000001, and a triangle's angles must add up to 180°.
The angles of a triangle always add up to 180o. A right angle triangle has angle of 90o, 60o, 60o.
Complementary angles add up to ninety degrees. Triangles must hold 180. Taking these facts together, think of this: you have two angles in a triangle where they add up to ninety. This means that the other angle in the triangle must hold the other ninety. I'm not going to answer your question, but I'll pose you the question you should have asked: What is a triangle called when it has one angle that is exactly ninety degrees?
A complementary angle is when two angles add up to 90o.
Interior angles are angles on a triangle that add up to 180
Two angles of a triangle add up to 65°. What is the measure of the third angle?
The interior angles of a triangle add to 180 degrees. This is true for any triangle, whether it is obtuse angled, right angles or acute.
A right angle triangle has only 1 right angle of 90 degrees and two acute angles that add up to 90 degrees whereas the 3 angles add up to 180 degrees
A right angle triangle has a 90 degree angle and two acute angles and the 3 angles add up to 180 degrees
No-An equilateral triangle has equal angles, an obtuse angle is greater than 90. So, an equilateral triangle with an obtuse angle would have the three angles add up to a MINIMUM of 270.0000000000001, and a triangle's angles must add up to 180°.
A right angle triangle has a 90 degree angle and two acute angles which all add up to 180 degrees
The angles of a triangle always add up to 180o. A right angle triangle has angle of 90o, 60o, 60o.
The exterior angles of a triangle add up to 360 degrees.
A right angle triangle has a 90 degree angle and its other two angles add up to 90 degrees
