Across
  1. 2. a straight line that connects two opposite corners of a shape, like a rectangle or a square. It cuts across the shape, dividing it into two parts.
  2. 4. a line that bends smoothly without sharp angles. It can go in any direction and can be open or closed, like the shape of a circle or the path of a winding road.
  3. 5. a series of straight lines that are connected by points, but the line does not stay continuous. It looks like a zigzag or has sharp turns between the points.
  4. 7. an angle that is smaller than 90 degrees. It looks sharp and narrow.
  5. 13. the amount of space inside a shape. It is measured in square units, like square meters or square centimeters. To find it, you use different formulas depending on the shape.
  6. 14. the place where two or more lines, roads, or shapes meet or cross each other.
  7. 16. an angle that is greater than 90 degrees but less than 180 degrees. It looks wider than a right angle.
Down
  1. 1. a three-dimensional shape with two identical circular bases that are parallel to each other. The sides of it are curved and connect the two bases.
  2. 3. two straight lines that intersect or cross each other at a right angle (90 degrees). This means they meet in such a way that the angle between them is exactly 90 degrees
  3. 6. a straight line where two surfaces of a 3D shape meet. It is the boundary between two faces, like the sides of a cube or a pyramid.
  4. 8. the total length of the sides of a shape. To find it for a polygon, you add up the lengths of all its sides.
  5. 9. a triangle that has two sides of the same length. The angles opposite these two equal sides are also the same.
  6. 10. a three-dimensional shape that is perfectly round. Every point on its surface is the same distance from its center. It is like a ball or a globe.
  7. 11. the distance from the center of the circle to any point on its edge. In the same circle they are all the same length.
  8. 12. a flat shape with five straight sides and five angles.
  9. 15. two straight lines that run in the same direction and never meet, no matter how far they are extended. They are always the same distance apart from each other at every point.
