Clockwise : Clockwise specifies a direction of a rotation in the same direction as the direction in which the hands of a clock are moving.
Counterclockwise : Counterclockwise specifies a direction of a rotation in the opposite direction of the direction in which the hands of a clock are moving.
Point : A point is an element in a space. Shapes are made of sets of points.
Right angle : A right angle is an angle equal to $90^{\circ}.$
Right triangle : A right triangle is a triangle that has a right angle. The sides that form the right angle are called legs, the third side is called hypotenuse. The area of a right triangle is half the product of the lengths of the two legs. The Pythagorean theorem is an important theorem for right triangles that allows to calculate the third side of a right triangle given the other two.
Rotation : A rotation is a transformation that turns a shape around. A rotation turns shapes into congruent shapes.
Which of the figures do you get if you rotate the right triangle in the upper part of the picture by $45^{\circ}$ counterclockwise?
