If we think about a rectangle, it's defined as having four right angles.
00:05
It is a parallelogram.
00:10
All sides do not have to be congruent, even though they can sometimes do when it's a square, but it's definitely all angles are right angles.
00:17
That's its definition.
00:18
Opposite sides are the same length.
00:23
Diaginals are the same length as well.
00:27
Opposite sides are parallel because it's a parallelogram.
00:30
And consecutive sides would be sides next to each other.
00:32
They're not necessarily congruent.
00:34
Usually they're not.

Properties of special quadrilaterals.

So which ones have all sides the same length? that is the definition of the rhombus, but a square is also a rhombus, so it also has all sides congruent.
00:50
Both pair of opposite sides congruent.
00:55
Opposite sides are congruent in a rectangle, a rhombus, and a square...
