What are the characteristics of a parallelogram?
Parallelograms: 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. 2.) opposite sides of a parallelogram are congruent 3.) diagonals bisect each other 4.)opposite angles are congruent 5.) consecutive angles are supp. *Remember that alternate interior angles are congruent.
Is a triangle and rectangle congruent?
No, a triangle and a rectangle are not congruent. Congruent means exactly the same size and shape. A triangle has 3 sides while a rectangle has four. A triangle's three angles always add up to 180 degrees where as a rectangle's four right angles always equal 360 degrees. They are not congruent- not even similar- at all.
How many diagonals does a 100 sided polygon Have?
100 sided polygon has = n(n-3)/2 diagonals = 100(100-3)/2 = 4850 diagonals
How many diagonals does a heptagon have?
A polygon with n sides has n(n-3)/2 diagonals. A heptagon has 7 sides giving it 7(7-3)/2 = 14 diagonals.
How many diagonals are in a 14 sided polygon?
The formula for finding the amount of diagonals in a polygon is n(n-3)/2. So 14(14-3)/2 = 77 Diagonals
What is a quadrilateral with two pairs of parallel lines?
It can be :- 1- a parallelogram 2- Square if diagonals are perpendicular and congruent 3- Rectangle if diagonals are congruent 4- Rhombus if diagonals are perpendicular
What shape does 3 congruent quadrilaterals make?
a big quadrilateral
How do you divide a hexagon into 3 parts to get 3 congruent quadrilaterals?
Assuming you have a regular hexagon, drawing a line between every other vertex and the center will give you three congruent quadrilaterals (that also happen to be parallelograms... in fact, they are rhombuses).
What are 3 possible quadrilaterals that have parallel sides and that are also congruent?
wht is the multiples of 23. and it is 52
3 things unique about a rectangle?
It is a parallelogram with 4 right angles and it has congruent diagonals that bisect.
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
Does a parallelogram always have 3 diagonals?
No sucka
What are fifteen or more facts and features relevant to geometrical quadrilaterals?
You're supposed to ask only one question at a time but here we go for 15 or more questions about quadrilaterals:- 1 Quadrilaterals are 4 sided 2 dimensional polygons 2 Quadrilaterals have 4 interior angles that add up to 360 degrees 3 Quadrilaterals have 4 exterior angles adding to 360 degrees 4 Quadrilaterals have 2 diagonals 5 Quadrilaterals have a perimeter which is the sum of their 4 sides 6 Quadrilaterals have areas with formulae depending on their types 7 Quadrilaterals can individually tessellate 8 Quadrilaterals can be split into 2 triangles 9 Quadrilaterals can be squares 10 Quadrilaterals can be rectangles 11 Quadrilaterals can be parallelograms 12 Quadrilaterals can be rhombuses 13 Quadrilaterals can be trapezoids or trapeziums 14 Quadrilaterals are sometimes isosceles trapezoids 15 Quadrilaterals can look like kites 16 Quadrilaterals can undergo transformations on the Cartesian plane 17 Quadrilaterals are congruent or similar when identical in angles and shapes 18 Quadrilaterals can form the cross-section of prisms 19 Quadrilaterals sometimes have lines of symmetry 20 Quadrilaterals have certain properties within a circle 21 Quadrilaterals can be subjected to trigonometry QED by David Gambell
What quadrilateral always has 3 congruent angles?
triangle
Does a quadrilateral have exactly 3 congruent angles?
A quadrilateral is ANY closed figure with 4 sides. Therefore, it also has 4 angles - any of which may, or may not, be congruent. About the only general statement about angles that applies to all quadrilaterals is that the sum of the angles is 360 degrees. By the way, it is possible for a quadrilateral to have 3 congruent angles, and the fourth angle not be congruent with the other 3.
Does an obtuse triangle always have 3 congruent sides?
An obtuse triangle does not always have three congruent sides. An obtuse triangle can be any form that always has three angles.
Does a quadrilateral always have 3 congruent angles?
No. Very few of them do.
