rhombus
360
Yes they are. It's a postulate: In a plane two lines perpendicular to the same line are parallel.
They would all add up to 360 degrees total.
Valley Tin is used on roofs where two roofs section meet perpendicular forming a valley. This creates a transitional for water to drain from both sides of the valley roofs. Two types of Valley Tin can be used, smooth/rolled metal or metal with an inverted V in the center. The inverted V serves to check the water speed on steep roofs to prevent an overshot of water causing a leak in the adjoining roof. Three metals are common in fabricating valley tins. Aluminum, Galvanized Metal & Copper
Sure, a square is a rectangle and the diagonals of a square are perpendicular.
quadrilateral
If you are talking about the diagonals of a quadrilateral, the only quadrilateral that have diagonals that are perpendicular and bisect each other is a square, because a rectangle has bisecting diagonals, while a rhombus has perpendicular diagonals. And a square fits in both of these categories.
The quadrilateral that must have diagonals that are congruent and perpendicular is the square. This is because its diagonals form a right angle at its center.
Rhombus
No.
If the diagonals of a quadrilateral are perpendicular to each other, then the quadrilateral is a square.Or a kite.
While it is true that if a quadrilateral has perpendicular diagonals, it can indicate that the shape is a rhombus, this condition alone is not sufficient for classification. Other quadrilaterals, such as kites, can also have perpendicular diagonals. Therefore, while perpendicular diagonals are a characteristic of rhombuses, they do not definitively determine that a quadrilateral is a rhombus without additional properties being met.
yes. A kite is not a rhombus, but has perpendicular diagonals.
false
One answer is a kite.
A square
