1. 1. Triangle:A scalene triangle can be defined as a triangle whose all three sides have different lengths, and all three angles are of different measures.
2. 4. an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
3. 10. in mathematics is a concept originating in geometry.
4. 15. quadrilateral with at least one pair of parallel sides is called a trapezoid in American and Canadian English.
5. 18. :n
6. 19. line In geometry, parallel lines are coplanar infinite straight lines that do not intersect at any point.
7. 21. A circle is a shape consisting of all points in a plane that are at a given distance from a given point,
8. 22. Euclidean geometry, a translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction.
9. 25. mathematics, the image of a function is the set of all output values it may produce. \
10. 27. Infinitely long line
##### Down
1. 2. In geometry a quadrilateral is a four-sided polygon, having four edges and four corners.
2. 3. Euclidean plane geometry, a rectangle is a quadrilateral with four right angles.
3. 5. preimage (plural preimages) (mathematics) For a given function, the set of all elements of the domain that are mapped into a given subset of the codomain
4. 6. Triangle In geometry, an isosceles triangle is a triangle that has two sides of equal length.
5. 7. plane Euclidean geometry, a rhombus is a quadrilateral whose four sides all have the same length.
6. 8. symmetrys the property a shape has when it looks the same after some rotation by a partial turn.
7. 9. When viewed as a vector, a ray is a vector from a point to a point
8. 11. In Euclidean geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angle
9. 12. A primitive notation that shows an exact point in space
10. 13. Euclidean geometry, a kite is a quadrilateral with reflection symmetry across a diagonal.
11. 14. of rotation: In mathematics, the angle of rotation is a measurement of the amount, of namely angle, that a figure is rotated about a fixed point,
12. 16. geometry, a vertex is a point where two or more curves, lines, or edges meet
13. 17. line: n elementary geometry, two geometric objects are perpendicular if they intersect at a right angle.
14. 20. In mathematics, a reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis or plane of reflection.
15. 23. mathematics, a rigid transformation is a geometric transformation of a Euclidean space that preserves the Euclidean distance between every pair of points.
16. 24. triangle: A scalene triangle can be defined as a triangle whose all three sides have different lengths, and all three angles are of different measures.
17. 26. In geometry, two figures or objects are congruent if they have the same shape and size,
