All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
true. and all things being equil(excuse me) the internal angles are all going to be 60degrees as we know that the internal angles of all triangles must add up to 180. see euclid. cheers.
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
All 3 angles and all 3 sides are the same
They are all called f angles or corresponding angles!
The angles in a square are congruent true or false
true:right angles are similar
No. A Rhombus has two obtuse angles and two acute angles

That all interior angles are equal in size.
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
