Mathematics Florida Standards (MAFS.912) for Geometry SY21
Note: These are the Student-friendly versions of the MAFS which all begin with, "The student will . . . " as listed in Math Nation's Teacher Area Guides (as linked for each section).
G-CO.2.6
use rigid motions to transform a figure.
explain the effect of a rigid motion on a figure.
determine if two figures are congruent after transformations have occurred.
G-CO.2.7
identify corresponding pairs of sides and corresponding pairs of angles on two triangles.
explain how two triangles are congruent.
G-CO.2.8
recognize triangle congruence (ASA, SAS, SSS) in terms of rigid motions that preserve distance (S) and angle (A).
show how preserving correlating distances (S) and angles (A) between two triangles results in congruence.
apply congruence to solve problems.
use congruence to justify steps within the context of a proof.
G-CO.3.10
prove theorems about triangles.
use theorems about triangles to solve problems.
G-GPE.2.7
use coordinates to compute perimeters of polygons and areas of triangles and rectangles.
G-SRT.2.4
use triangle similarity to prove theorems about triangles.
prove the Pythagorean Theorem using similarity.
G-SRT.2.5
apply the concepts of congruence and similarity criteria to solve problems involving triangles.
apply the concepts of congruence and similarity criteria to prove relationships in geometric figures.
G-C.1.3
construct a circle inscribed inside and circumscribed about a triangle.
solve problems using the properties of inscribed and circumscribed circles of a triangle.
use or justify properties of angles for a quadrilateral inscribed in a circle, such as opposite angles in an inscribed quadrilateral are supplementary.
G-CO.3.10
prove theorems about triangles using deductive reasoning.
use theorems about triangles to solve problems.
G-SRT.1.2
explain similarity in terms of similarity transformations that corresponding angles of two figures are congruent and that corresponding sides of two figures are proportional.
use the definition of similarity to determine if two figures are similar, including triangles.
G-SRT.1.3
explain using properties of similarity transformations why the AA criterion is sufficient to show that two triangles are similar.
G-SRT.2.5
apply the concepts of congruence and similarity criteria to solve problems involving triangles.
apply the concepts of congruence and similarity criteria to prove relationships in geometric figures.
