Across
- 1. When a shape is rotated by an angle greater than 0° but less than or equal to 180° and is able to look like the original shape. △ This triangles' __________ is 3, when turned 0°, 120°, and 240° counterclockwise.
- 4. To mirror a shape across a line, such as flipping △ABC across the y-axis to form △XYZ
- 5. Angles congruent and opposite to each other.
- 9. Shape before a transformation. The ______ of □ before a translation 4 units to the right and 2 units down.
- 12. A triangle with angle measures of 60°. All sides are congruent.
- 13. This usually makes the shape of a coordinate plane. Two lines forming 90° and cutting each other exactly in half.
- 14. A triangle with at least two congruent sides
Down
- 2. To slide a shape without changing anything but its position on a coordinate plane.
- 3. Angles that when added form a right angle. 24°+46°+x°=90°.
- 6. Also known as reflection symmetry. When cut in half, the shape should map onto itself, meaning it should be the same shape when its cut in half.
- 7. A 90° angle is cut in half, making two 45° angles.
- 8. A line intersecting parallel lines to form corresponding angles, alternate interior angles, and same side interior angles.
- 10. To turn an object clockwise or counterclockwise at a certain angle without changing itsshape, such as turning △ABC 270° counterclockwise to form △XYZ.
- 11. Can be done in a sequence or in singular. This can include transformations such as relfection, translation, and rotation, which does not change the size or shape of the preiamge.
- 15. Having the same shape and size. Can be applied to any shape. Some examples of _______ triangles are triangles defined by ASA, SSS, SAS.
