Across
- 3. is a type of polygon, which has three sides, and the two sides are joined end to end is called the vertex of the triangle.
- 4. is a four-sided closed shape or figure which cover some area and also has its perimeter.
- 7. is a quadrilateral that has the following four properties: Opposite angles are always equal
- 9. is a closed two-dimensional figure formed by joining the four points among
- 10. is often referred to as convex down or concave upward, and the term concave is often referred as concave down or convex upward.
- 11. It is a quadrilateral with one pair of opposite parallel sides.
Down
- 1. is a quadrilateral with two pairs of parallel sides.
- 2. a polygon having four sides, four angles, and four vertices.
- 5. function is a mathematical function that has a downward curve, meaning that any line segment drawn between any two points on the graph of the function will lie below or on the graph.
- 6. is a flat shape with straight sides. It has two pairs of equal-length adjacent (next to each other) sides. It often looks like.
- 7. is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles.
- 8. has four axes of symmetry, and its two finite diagonals (as with any rectangle) are equal. Bisection of a square by a diagonal results in two right triangles.
