How do you find the measure of the sides of a rhombus by its diagonals?
The diagonals of a rhombus bisect one another at right angles. So you can use Pythagoras on half the lengths of the diagonals. If the two diagonals ore of lengths a and b, then side2 = (a/2)2 + (b/2)2 or, equivalently, side = 1/2*sqrt(a2 + b2)
How do you find the sides of a rhombus if diagagonal are given?
The diagonals bisect each other at right angles. So you could use Pythagoras on half the diagonals. So, if the diagonals are a and b units long, then half the diagonals are a/2 and b/2 units long. Then, by Pythagoras, the sides of the rhombus are sqrt[(a/2)2 + (b/2)2]
What 2d shape has 4 sides 2 acute angles 2 obtuse angles diagonals intersect at right angles and 2 pairs of adjacent sides equal in lenght?
A kite.
What are facts about parallelogram?
Opposite sides are congruent Opposite sides are parallel Opposite angles are equal Consecutive angles are supplementary Diagonals bisect each other Diagonals form 2 equal triangles
What are the 2 charcteristic's of the rhombus?
There are many characteristics of a rhombus. Every rhombus is a parallelogram, so it has all the characteristics of one: opposite sides are parallel, adjacent angles are supplementary, and the diagonals bisect each other. Additionally, there are two other characteristics that apply to rhombuses: the opposite angles are congruent and the diagonals are perpendicular.
What shape has 2 congruent diagonals that do not bisect?
A trapezoid Trapezoid - 2 congruent diagonals that do not bisect each other. No right angles and has 1 pair of opposite parallel sides.
Diagonal of a square?
A square has 2 diagonals that are equal in length and bisect each other at right angles.
Do the diagonals bisect angles in a quadrilateral?
There are 4 angles in quadrilateral. 2 angles bisected would yield 2 each 45 degrees angles (or less) and the other 2 angles would yield (bisected ) 45 degrees (or more)!
What are the properties for a rhombus?
It is a 2D shape that has 4 sides It belongs to the class of polygons known as quadrilaterals It has 4 equal sides It has 2 equal obtuse angles and 2 equal acute angles It has 2 diagonals that bisect each other at 90 degrees Its 4 interior angles that add up to 360 degrees
How do you find the measure of the sides of a rhombus by its diagonals?
The diagonals of a rhombus bisect one another at right angles. So you can use Pythagoras on half the lengths of the diagonals. If the two diagonals ore of lengths a and b, then side2 = (a/2)2 + (b/2)2 or, equivalently, side = 1/2*sqrt(a2 + b2)
What properties does a rectangle have?
Two sets of parallel sides. Four right angles. Opposite sides are congruent. The diagonals bisect each other. The diagonals make 2 congruent triangles. Is also a parallelogram.

What are four attributes of a rhombus?
1. Opposite angles congruent 2. All sides are congruent 3. The diagonals are perpendicular bisectors of each other 4. Diagonals bisect the angles NOTE: Four congruent right triangles are formed with the right angles It has all of the properties of a parallelogram and a kite
What shape has 4 right angles 2 diagonals and 4 axes of symmetry?
Parrellelagram
Why square is a rectangle?
The definition of a rectangle: A figure that has 4 right angles, has congruent diagonals that bisect, has 2 pairs of parallel sides, and has 2 pairs of opposite congruent angles. A square has all of the above, and thus, is a rectangle by definition.
What 2d shape has 4 sides 2 acute angles 2 obtuse angles diagonals intersect at right angles and 2 pairs of adjacent sides equal in lenght?
A kite.
What are 10 characteristics of a square?
1. 4 equal sides 2. Opposite sides are parallel 3. 4 equal angles 4. Exterior angles add to 360 5. Interior angles add to 360 6. Length of diagonals are equal 7. Diagonals bisect each other 8. Diagonals are perpendicular 9. Can be separated diagonally into 2 congruent triangles 10. A square is a "regular" polygon
