Same side interior angles are congruent to their vertical angles.
Yes, the opposite interior angles of a parellelogram are equal.
Only when it is a regular polygon that all interior angles are of equal measure
Any polygon can have 3 equal interior angles, but it doesn't have to.An equilateral triangle always has 3 equal interior angles.
If all of its interior angles are equal then it is a regular polygon
That all interior angles are equal in size.
Same side interior angles are congruent to their vertical angles.
Opposite interior acute and obtuse angles are equal
Yes, the opposite interior angles of a parellelogram are equal.
Only when it is a regular polygon that all interior angles are of equal measure
Any polygon can have 3 equal interior angles, but it doesn't have to.An equilateral triangle always has 3 equal interior angles.
The main difference is that a parallelogranm has 2 interior equal obtuse angles and 2 interior equal acute angles whereas a rectangle has 4 equal interior right angles
If all of its interior angles are equal then it is a regular polygon
The 4 interior angles add up to 360 degrees
No because it has 2 equal interior acute angles and 2 equal interior obtuse angles but its 4 sides are equal in length
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
