Across
- 4. Quadrilateral Also known as a crossed quadrilateral, it is a type of quadrilateral having self-intersecting sides.
- 5. It is a quadrilateral with one pair of opposite. parallel sides. ABCD, side AB is parallel to side CD.
- 10. is a trapezoid with congruent base angles and congruent non-parallel sides. A trapezoid is a quadrilateral with only one of its sides parallel.
- 11. if at least one diagonal, i.e. the line segment joining the vertices is not a part of the same region of the quadrilateral.
- 13. Only one pair of the opposite side of a trapezium is parallel to each other. The two adjacent sides of a trapezium are supplementary (180 degrees)
- 14. It is a quadrilateral in which all the sides and angles are equal. Every angle is a right angle (i.e. 90° each). The pairs of opposite sides are parallel to each other.
Down
- 1. Three different triangles are placed together to form a quadrilateral ABCD. Determine the classification of the quadrilateral.
- 2. It is a quadrilateral with all four sides having equal lengths. The Opposite sides of a rhombus are parallel and opposite angles are equal.
- 3. It is a quadrilateral with two pairs of parallel sides. The opposite sides are parallel and equal in length. The opposite angles are equal in measure. In the parallelogram, ABCD, side AB is parallel to side CD and side AD is parallel to side BC.
- 4. a four-sided polygon that has interior angles that measure less than 180 degrees each.
- 6. A diagonal of a quadrilateral is a line segment whose end-points are opposite vertices of the quadrilateral.
- 7. Quadrilaterals are not simple quadrilaterals in which the pair of non-adjacent sides intersect. These kinds of quadrilaterals are known as self-intersecting or crossed quadrilaterals
- 8. It is a quadrilateral that has 2 pairs of equal-length sides and these sides are adjacent to each other.
- 9. are joined together to form another quadrilateral. Determine the classification of the polygon ABCD.
- 12. It is a quadrilateral with all the 4 angles of equal measure, that is, each of them is 90°. Both the pairs of opposite sides are parallel and equal in length.
