A four-sided shape has four congruent angles and sides. Which quadrilateral could it be? A. quadrilateral B. trapezoid C. square

Gnoma [55]

Answer:

C. square

Step-by-step explanation:

Congruent means "the same" (having the same shape and size).

Any four-sided, 2-dimensional shape with straight sides is called a quadrilateral.

There are 6 special types of quadrilaterals:

Rectangle

Opposite sides are parallel and equal in length
All interior angles are 90°

Square

All sides are equal in length
All interior angles are 90°

Rhombus

All sides are equal in length
Opposite sides are parallel
Opposite angles are equal

Parallelogram

Opposite sides parallel and equal in length
Opposite angles are equal

Trapezoid

One pair of opposite parallel sides

Isosceles Trapezoid

One pair of opposite parallel sides
One pair of non-parallel sides equal in length
Two pairs of equal base angles

Kite

Two pairs of adjacent sides equal in length
The angles included between the sides of differing lengths are equal

Conclusion

A four-sided shape that has four congruent angles and sides is a SQUARE.

A set is a mathematical model for a collection of items. The correct option is C.

A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.

Given the s={(a, b), (a, c), (b, d), (d, c)} and t={(b, b), (c, a), (c, d), (a, d)} Therefore, the value of t ∘ s = { (a, c), (b, d), (c, b), (c, c) }.

Hence, the correct option is C.
