Note: #17: lines that appear to
be parallel are parallel.
G1.2 Triangles and Their Properties
G1.2.1
1). I can write a two-column proof of the following theorem: The sum of the angles of a triangle
is 180o.
2). I can find the measure of a missing angle of a triangle.
G2.3 Congruence and Similarity
G2.3.3
1). I can write a two-column proof showing that two triangles are similar using SSS~, SAS~,
and AA~ postulates.
G2.3.4
1). I can determine if two triangles are similar, given information about their sides and angles.
2). I can solve a proportion.
3). I can find the ratio of two numbers.
4). I can calculate the geometric mean of two numbers.
5). I can write a proportion using the sides of similar triangles.
6). I can write a proportion using the cross products theorem.
7). I can find the length of a segment using the theorem that states that a ray that bisects an angle
of a triangle divides the opposite side into segments whose lengths are proportional to the
lengths of the other two sides (theorem 6.7).
8). I can find the length of a segment using the triangle proportionality theorem or its converse
(theorems 6.4 and 6.5).
9). I can solve for missing sides or angles of similar shapes.
10). I can find the length of a segment using the theorem that states that two transversals divide
3 parallel lines proportionally (theorem 6.6).
