parallel lines, alternate interior angles are congruent and
corresponding angles are congruent; points on a perpendicular
bisector of a line segment are exactly those equidistant from the
segment's endpoints.
12. [G-CO.12] Make formal geometric constructions with a variety
of tools and methods such as compass and straightedge, string,
reflective devices, paper folding, and dynamic geometric
software, etc. Constructions include copying a segment; copying
an angle; bisecting a segment; bisecting an angle; constructing
perpendicular lines, including the perpendicular bisector of a line
segment; and constructing a line parallel to a given line through a
point not on the line.
10. [G-CO.10] Prove theorems about triangles. Theorems include
measures of interior angles of a triangle sum to 180o, base angles
of isosceles triangles are congruent, 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.

7. [G-CO.7] Use the definition of congruence in terms of rigid
motions to show that two triangles are congruent if and only if
corresponding pairs of sides and corresponding pairs of angles are
congruent.
8. [G-CO.8] Explain how the criteria for triangle congruence,
angle-side-angle (ASA), side-angle-side (SAS), and side-side-side
(SSS), follow from the definition of congruence in terms of rigid
motions.
10. [G-CO.10] Prove theorems about triangles. Theorems include

half the length, the medians of a triangle meet at a point.

30. [G-GPE.4] Use coordinates to prove simple geometric
theorems algebraically. Example: Prove or disprove 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).

9. [G-CO.9] Prove theorems about lines and angles. Theorems
include vertical angles are congruent; when a transversal crosses
parallel lines, alternate interior angles are congruent and
corresponding angles are congruent; points on a perpendicular
bisector of a line segment are exactly those equidistant from the
segment's endpoints.
26. [G-C.3] Construct the inscribed and circumscribed circles of a
triangle, and prove properties of angles for a quadrilateral
inscribed in a circle.

of isosceles triangles are congruent, 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.
26. [G-C.3] Construct the inscribed and circumscribed circles of a
triangle, and prove properties of angles for a quadrilateral
inscribed in a circle.
4. [G-SRT.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 the center unchanged. ~The dilation of a line
segment is longer or shorter in the ratio given by the scale factor.
15. [G-SRT.2] Given two figures, use the definition of similarity in
terms of similarity transformations to decide if they are similar;
explain using similarity transformations the meaning of similarity
for triangles as the equality of all corresponding pairs of angles
and the proportionality of all corresponding pairs of sides.
