    \nQuestion 1.
    \nScott sorted these shapes. Put an X on the one that does not belong.
    \n\"Envision
    \nAnswer:
    \n\"Envision-Math-Common-Core-1st-Grade-Answer-Key-Topic-14-Reason-with-Shapes-and-Their-Attributes-2\"
    \nExplanation:
    \nIn the above image we can observe 4 shapes one is square, second is rectangle, third is also rectangle and fourth is circle. Both Square and rectangle have four edges and four vertices. Circle has 0 edges and 0 vertices. So draw X on the circle which is different from the above three shapes.<\/p>\n

    \nThe above shape is right angled triangle which is different from the above shape.
    \nExplanation:
    \nHere we have to draw a shape which is different from the square shape. In geometry, a square is a regular quadrilateral, it has four equal sides and four equal angles. It can also be defined as a rectangle in which two adjacent sides have equal length.
    \nHere I drawn right angled triangle. A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

    \nJeff needs to add one shape to the above arrow. Here we have four options. Option A is a hexagon and option B is a trapezium, option C is a parallelogram, and option D is a triangle. Here triangle is the correct match to the above image. So Jeff needs to add a triangle to his model to finish the arrow. So make a tick mark to option D.<\/p>\n

    \nThe above object has two flat surfaces and zero vertices. The object is a cylinder.
    \nExplanation:
    \nIn mathematics, a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis. The cylinder has two flat surfaces and zero vertices.<\/p>\n
