Quadrilateral abcd is a square bc equals 10 what is the length of ac?
If the quadrilateral is a square then all of its sides are the same length. ac is not one of the sides but is a diagonal which forms the hypotenuse of a right angle triangle with sides ab and bc. According to Pythagoras the sum of the square of the hypotenuse is equal to the sum of the squares of the other two sides. As side ab measures 10 then 10 squared = 100. Side bc has the same measurements. The square of side ac must equal 200 (100 + 100) so the length of side ac must equal the square root of 200 (100 + 100) which is 14.14 (to 2 decimal places).
What is the perimeter of the quadrilateral?
The perimeter of a quadrilateral is 'side + side + side + side = perimeter'. If the quadrilateral is a square, you can simplify this to 'side x 4 = perimeter'.
What quadrilateral had two different pairs of equal length side?
rectangle,square and parallelogram in general.
Draw equiangular quadrilateral that is not regular?
An equiangular quadrilateral is a four-sided figure with all angles equal. To draw an equiangular quadrilateral that is not regular, you would need to create a shape where all four angles are equal but the side lengths are not necessarily equal. One way to do this is to draw a square and then elongate one pair of opposite sides while keeping all angles at 90 degrees. This will result in a shape that has equal angles but different side lengths, making it an equiangular quadrilateral that is not regular.
Name a quadrilateral with 3 equal sides but no parallel lines?
There is no particular name for such a shape.
