A rotation of a tetromino is a circular movement of it around a centre (or point) of rotation. We need to observe the pattern and fill up the box. In the given problem, the tetromino is to be rotated by 270 ° . The required table is shown below.

A rotation of a tetromino is a circular movement of it around a centre (or point) of rotation. In the given problem, the tetromino is to be rotated by 180 ° . This can be done by rotating the tetromino present under 90 ° by 90 ° in clockwise direction. Similarly, to rotate the given tetromino by 270 ° , rotate the tetromino present under 180 ° by 90 ° in clockwise direction. Hence, the required table is

A rotation of a tetromino is a circular movement of it around a centre (or point) of rotation. In the given problem, the tetromino is to be rotated by 90 ° . This can be done by rotating the tetromino by 90 ° in clockwise direction. On rotating the tetromino by 360 ° , we get the same object present in original position. Hence, the required table is

Using the given Tetromino shaded in two different ways Fill grid in such a way that, no two adjacent boxes have the same colour.

A tetromino is a geometric shape composed of four squares. Using the given tetromino, The given grid can be filled in the following way. And the tetrominoes are arranged in such a way that, no two adjacent boxes have the same colour.

Match the tetrominoes of same type. (i) (ii) (iii) (iv)

A tetromino is a geometric shape composed of four squares by joining edge to edge. In the given problem, a tetromino present on the left-hand side is rotated through a certain angle to get a resulting tetromino that matches the right-hand side. Hence, the required answer is (i) (ii) (iii) (iv)

Using the given tetrominoes with numbers, complete the 4 × 4 magic square.

A magic square contains numbers arranged in equal rows and columns such that the sum of each row, column, and diagonal is the same. The given tetrominoes with numbers can be arranged in the given 4 × 4 magic square as shown below: It can be observed that, sum of numbers along any row, column or diagonal is equal to 34 .
