Unit 5 Vocabulary
Angle A figure formed by 2 rays with a common endpoint. The angle is
Circle The set of points on a plane at a certain distance, or radius, from a single point, the center
Perpendicular Line Two lines that intersect at a right angle (90°). Written as
Parallel Line Lines in a plane that either do not share any points and never intersect, or share all points. Written as
Line Segment A line with two endpoints. Written as
Point Point A or Point B An exact position or location in a given plane.
Line The set of points between points P and Q in a plane and the infinite number of points that continue beyond the points. Written as
Distance along a line The linear distance between two points on a given line.
Right Angle An angle that measures 90°.
Acute Angle An angle measuring less than 90° but greater than 0°.
Obtuse Angle An angle measuring greater than 90° but less than 180°.
One-to-One A relationship wherein each point in a set of points is mapped to exactly one other point.
Pre-image The original figure before undergoing a transformation.
Image The new, resulting figure after a transformation
Isometry A transformation in which the preimage and image are congruent.
Rigid transformations can also be referred to as an ISOMETRY. Every segment is congruent to its image. Transformations are called RIGID if every image is congruent to its preimage.
Which of the following are rigid transformations? (Isometry)
Find the value of each variable, given that the transformation is an isometry.
Congruent Figures are congruent if they have the same shape, size, lines, and angles.
Similar Triangles Triangles are similar if they have the same shape but have different sizes.
