Term | Definition |
---|---|
Translation | A slide of a figure |
Rotation | A turn of a figure either clockwise or counter-clockwise |
Reflection | A flip of a figure across an axis or line |
Dilation | A reduction or enlargement of a figure |
Congruent | Having the same shape and/or measurement |
Similarity | Two figures that are the same shape but a different size |
Exterior Angles | Angles located outside of (above or below) the parallel lines. |
Interior Angles | Angles located inside of the parallel lines. |
Alternate Interior Angles | Angles on opposite sides of the transversal located inside the two lines cut by the transversal. They are congruent to each other. |
Alternate Exterior Angles | Angles on opposite sides of the transversal located outside the two lines cut by the transversal. They are congruent to each other. |
Corresponding Angles | Angles located in the same relative position on the two lines cut by the transversal. They are congruent to each other. |
Same-side Interior Angles | Two angles that sit either on the left or the right side of the transversal in between the two parallel lines. |
Vertical Angles | Opposite angles formed by intersecting lines. These angles are congruent to each other. |
Complementary | Two angles whose sum is 90˚. |
Supplementary | Two angles whose sum is 180˚ |
Transversal | A line that intersects two or more other lines |
Parallel Lines | Two lines that never intersect (they must run side by side) |
Right Triangle | A triangle that has one 90 degree angle. |
Hypotenuse | The longest side of a right triangle that is opposite of the right angle. |
Legs | The two perpendicular sides that create the right angle. |
Radius | Extends from the center of the circle to one side of the circle. (It only goes halfway) |
Volume | The amount of space enclosed inside a figure. (think of filling a pool) |
Height | Vertical distance (must run up and down) |
