An isosceles triangle has two equal angles and one different angle. The sum of the angles in any triangle is always 180 degrees. Therefore, the two equal angles in an isosceles triangle must add up to 180 degrees minus the different angle. So, each of the two equal angles in an isosceles triangle measures (180 - x) / 2 degrees.
Exterior and interior angles at the vertex of a triangle add up to 180 degrees
Well, honey, the biggest angle you can have in a triangle is 180 degrees. That's because the sum of all angles in a triangle is always 180 degrees. So if you've got one angle that's 180 degrees, the other two angles gotta be zero, which basically means you ain't got no triangle at all.
Yes it does. Good work!
Angle A + Angle B + Angle C = 180 degrees. 30+90+C=180 120+C=180 C=60 degrees.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
Interior angle+exterior angle = 180 degrees
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
The 3 exterior angles of any triangle add up to 360 degrees and the 3 interior angles add up to 180 degrees.
In any triangle exterior angle plus interior angles = 180 degrees
a triangle has 180 degree but each exterior has 90 degree .
It is: 180-interior angle = exterior angle
It is: 180-interior angle = exterior angle
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
The triangle has three exterior angles. Added together, their total is 180 degrees.(Same as the total of the three interior angles when they're added together.)
The sum of the interior angles of any triangle is 180 degrees.
