(a). All four sides are equal and the angles are right-angled (90 degrees).
(b). A quadrilateral has no pairs of parallel sides is a Kite and irregular trapezium.
(c). A triangle having one pair of equal sides and one pair of equal angles is an isosceles Triangle.
<h3>What is geometry?</h3>
One of the first areas of mathematics is geometry, along with arithmetic. It is focused on spatial characteristics that relate to the proximity, size, shape, and relative placement of objects.
(a). Two features that make the shape square are all four sides equal and the angles are right-angled (90 degrees).
(b). A quadrilateral has no pairs of parallel sides is a Kite and irregular trapezium.
(c). A triangle having one pair of equal sides and one pair of equal angles is an isosceles Triangle.

The answer is -42. A negative times a negative is a positive and a negative times a positive is a negative. If you multiply -6 x -7 you get 42. Then do 42 x-1 and you get -42.
The correct answer or sum for 1+1 is 2 because if you take 1 thing and put it with another thing, you now both have 2 things
Step-by-step explanation:
19/9 = 2.1111111111
<h2>so to round to the nearest thousandth means there should be 3 numbers after the decimal point (.) because a thousandth contains 3 zeros.</h2>
2.11111111111 to the nearest thousandth = 2.111
Hope this helps.
Good luck ✅.
