An interior angle is any angle on the interior of the triangle.
A triangle with a 90o interior angle is called a 'right' triangle. BTW, any triangle can have only one 90o interior angle
interior is the inside of a triangle but is connected to the triangle.
A heptagon. It can have a reflex interior angle, a triangle cannot.
You cannot.
They are all 60 degrees.
Either could have a larger interior angle. If they were regular, then the interior angle of a triangle would be 60 degrees whereas that of a heptagon would be 128.57 degrees. The REGULAR heptagon would have a larger interior angle than a REGULAR triangle.
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
Add the first two angles together and subtract the total from 180 to find the 3rd angle
It is: 180-interior angle = exterior angle
It is: 180-interior angle = exterior angle
a right triangle
