Congruence
Experiment with transformations in the plane

ions of point, line, distance
alon
g a line, and distance around a circular arc.
2. Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as func
tions that take points in
the plane as inputs and give other points as outputs. Compa
re transformations that preserve distance and angle to those that do not (e.g.,
translation versus horizontal stretch).
3. Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto
itself.
4.
Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel li
nes, and line segments.
5. Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using,
e.g., graph paper, tracing paper, or geometry
software. Specify a sequence of transformations that will carry a given figure onto another.
Understand congruence in terms of rigid motions
6. Use geometric descriptions of rigid motions to transform figures
and to predict the effect of a given rigid motion on a given figure; given two figures,
use the definition of congruence in terms of rigid motions to decide if they are congruent.
7. Use the definition of congruence in terms of rigid motions to show that t
wo triangles are congruent if and only if corresponding pairs of sides and
corresponding pairs of angles are congruent.
8. Explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of
rigid motio
ns.

angles are congruent and corresponding angles are congruent; points on a p
erpendicular bisector of a line segment are exactly those equidistant
from the segment’s endpoints.
10. Prove theorems about triangles.
Theorems include: measures of interior angles of a triangle sum to 180°; base angles of isosceles triangles are
congruen
t; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of
a triangle meet at
a point.
11. Prove theorems about parallelograms.
Theorems include: opposite sides are congruent, opposite angl
es are congruent, the diagonals of a
parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.
Make geometric constructions
12. Make formal geometric constructions with a variety of tools and methods (compass
and straightedge, string, reflective devices, paper folding,
dynamic geometric software, etc.).
Copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines,

egment; and constructing a line parallel to a given line through a point not on the line.
13. Construct an equilateral triangle, a square, and a regular hexagon inscribed in a circle.
Similarity, Right Triangles, & Trigonometry
Understand similarity i
n terms of similarity transformations
1. Verify experimentally the properties of dilations given by a center and a scale factor:
A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through
th
e center unchanged.
The dilation of a line segment is longer or shorter in the ratio given by the scale factor.
2. Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar;
explain using simil
arity
transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proporti
onality of all
corresponding pairs of sides.

4. Use coordinates to prove simple geometric theorems algebraically.
For example, prove or disp
rove that a figure defined by four given points in the
coordinate plane is a rectangle; prove or disprove that the point (1,
√3) lies on the circle centered at the origin and containing the point (0, 2).
5. Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equ
