M(G&M)–10–2 Makes and defends conjectures, constructs geometric arguments, uses geometric properties, or uses theorems to solve problems involving angles, lines, polygons, circles, or right triangle ratios(sine, cosine, tangent) within mathematics or across disciplines or contexts
1st identify the sides
List the angles in
1st- Find the side measures
2nd- Use the theorem to order the angles

1st, identify the angles
2nd, use the theorem to generalize the measures of the sides
List the sides of ABC from
Greatest to least
Find the value of x and list the sides of
ROT in order from least to greatest.
If 2 sides of 1 triangle are congruent to 2 sides of a 2nd triangle and the 3rd side in one triangle is _______ than the 3rd side in the 2nd triangle, then the ___________ in one triangle is ______ than the included angle in the 2nd.
