Sum of angles is 180, not 90
...a right triangle.
exterior angle theorem
In any triangle exterior angle plus interior angles = 180 degrees
The shape is a triangle.
Sum of angles is 180, not 90
The sum of the angles should equal 180
77. The sum of the three angles in a triangle equal the sum of 180 degrees
...a right triangle.
It's not. It's 180o.
170Apex(:
It is 1/2 of length x width
The sum of the interior angles of a triangle on a plane is always 180 degrees.
The theorem that states the angle measures in a triangle sum to 180 degrees is known as the Triangle Sum Theorem. This fundamental property of triangles applies to all types of triangles, regardless of their shape or size. It is often used in geometry to solve for unknown angles when given the measures of other angles in a triangle.
Exterior angle.
In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
