WebA rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent. There are several formulas for the rhombus that have to do with its: Sides (click for more detail) All 4 sides are congruent. Angles. Diagonals bisect vertex angles. Diagonals. WebMar 9, 2024 · The main difference is that a rectangle has 4 equal interior right angles whereas a parallelogram has 2 equal interior obtuse angles and 2 equal interior acute anglesBoth have two sets of parallel lines, but a rectangle forms four equal 90 degree angles. A parallelogram does not have four equal angles. WebAn angle is obtuse if its lies between 90 and 180 degrees. In this figure the interior angle of the triangle is two acute angles and an obtuse angle. So, the exterior angle is with two obtuse angles. Therefore, the triangle satisfies the above condition. Hence, a triangle cannot have two obtuse angles because the sum of all the angles cannot ... jean marc budin
